The CSIC clarifies that new magma spots are leaving for other parts of the fissure
Thursday, October 13, 2011 19:11 acnpress

The Technical Centre for Scientific Research (CSIC) Ramon Ortiz has clarified that the new spots during the evening have been producing more and more near the coast of La Restinga are associated with magma output from other parts of the same that takes days to crack open.

Thus, although at first there was talk of new cracks, Ortiz said that what happens is that "there is a gap of several kilometers and magma comes out one way or the other." Ortiz appeared next to the Director General of Security and Emergency of the Canary Islands, Juan Manuel Santana, members of the leadership of the Civil Protection Plan for Volcanic Risk (Pevolca).

Santana explained that, for now, "maintained the protection measures that have been decided: red light in La Restinga and yellow on the rest of the island." In addition, the autonomous responsibility of managing the crisis sismovolc?nica announced that, for now, is not going to open the tunnels Roquille, as requested by both the council and the municipalities of the Island "Our obligation is the safety of people do not pay attention to another set of criteria, "he said.

With respect to the spots that were observed this afternoon from La Restinga, where it appeared that magma came out again in a straight line to the east, closer and closer to the coast, Ortiz said that this phenomenon is known as Rayleigh-Taylor instability, with which "instead of always leaving the same place, now comes from one site and then by another."

The scientist's CSIF clarified that all possibilities are open about what might happen with the crack. "If you go to deeper waters will not see anything," and that beyond the 500 m deep water pressure prevents the release anything. As there is a stain, Ortiz took the risk to calculate the crack should be at a depth of 200 meters, since staining was observed to be between 150 and 500 meters.

"At the time the magma rise more and had only 40 or 60 meters above water would be in the most dangerous time in which it already had many explosions," he added.

The scientific presence in the area to study the evolution of the phenomenon will continue 24 hours a day "with instrumental and visual surveillance to detect if they start to show signs that indicate that the magma is very superficial," said Ortiz.

CANARY | Eruption in El Hierro

"The situation is ugly, no one knows what will happen '

Michel Martin | Valverde (El Hierro)
Updated Friday 14/10/2011 11:15

Ortiz CSIC researcher assessed the progress of the volcanic phenomenon that is living in El Hierro: "The magma is rising along the fissure is several kilometers long. It makes no sense to speak of eruptive mouths. The fundamental problem is knowing where their mouths are, "said scientist working to piece together the rest of the team awake 24 hours the visual phenomenon and instrumentally.

"Our mission is whether the eruption stops, if the crack will bring magma near the coast in the middle of the island, or be extended to the south and go into deeper waters," lists the assumptions of the performance of the phenomenon volcanic. "In a few hours we'll know, maybe a couple of days," the researcher resolved the uncertainty. "The important thing is not the spot, the important thing is that the activity continues."

Ramon Ortiz confirmed that the situation has changed little from Wednesday: "Today is like yesterday. Do not know yet if the fracture is close to the coast, so we're watching. The situation is ugly because no one knows what will happen. Every hour we analysis and forecasts and simulations all we can with our computers. "

Unknowns and uncertainties

Apart from the technical, once it seems that there is no direct danger, all you can be visible from the volcano is an attraction for the inhabitants of the island, along the journey to have come from areas which is more easily seen the remains of eruptions: two green spots in the water. Both are within a nautical mile (just under two miles) from La Restinga, the southernmost population of El Hierro.

The show, however, seems less enjoyable for local fishermen, who were concerned about the potential dangerousness of the substances expelled through the vents on the seafloor. In fact, the fleet remains tied to the expectation of clean water.

This will happen not in the short term. Although the authorities want to reduce the alarm do recognize that marine life will be affected for a variable period of time but, eventually, the area will benefit from the minerals that are emerging.

The volcanic spot and makes landfall in El Hierro.

Researchers from non-tip (volcanological Institute of the Canary Islands) confirmed that the stain to Public gases caused by underwater eruptions and El Hierro landfall, about six o'clock, at the tip of La Restinga. This village of 500 inhabitants, was evacuated on Tuesday because of its proximity to eruptive phenomena. Researchers still do not know the details of the stain and its evolution.

Indeed, to know those details, arrived at the port of Valverde Stake Ignacio Lozano oceanographic ship, the Canary Islands Institute of Marine Science. Earlier on Saturday Hierro port sail towards the large stain caused by the eruptive process began on Monday in front of the still desert village of La Restinga.

This boat has been received with satisfaction by the scientists working on the island, because you can solve many of the doubts that still glide between volcanologists who are following this crisis. What chemical is out of the sea? Is magma out of the crack, or just gas? In these studies involved researchers from the Spanish Institute of Oceanography, non-tip, the National Geographic Institute of the Canary Islands Oceanic Platform and the two universities in the islands.

"We are relatively unfamiliar with," says campaign manager

Carlos Barreda, chief scientist of this campaign, admitted that the first time faced a similar situation. "We came with some ignorance because it is a phenomenon that we have never seen but want to measure in the area," he explains. To perform the research, the ship has on board instruments you can measure the water column that is under the spot volcanism. "We are able to measure up to 1,500 feet deep, enough to work in the area." Barreda has recognized that the methodology of work is the same as in other campaigns. "As before, some of the water samples that we take will be analyzed on board and others will be sent to the laboratories of the Canarian universities."

To make this work, the six scientists on board will Nansen and Niskin bottles used, well known in oceanography instruments for collecting water samples at different depths and study of temperature, salinity, oxygen, nutrients or tracers. Although the crew has extensive experience in zoological studies, for now conduct research on how these emissions are affecting the fauna. "Our priority is to perform chemical and physical analysis of the stain which is south of the island to complete the volcanological studies." Experts who know the toxicity of volcanic gases have on board gas masks, gloves, boots and special suits.

The ship will depart for the south of the island to be placed over the area of ​​volcanic emissions, which make a first approach to the research plan. "We know when we arrived but when we're leaving," says the scientist. To complete the work of Ignacio Lozano, in the middle of next week will come to the island the meridian the ship of the Spanish Institute of Oceanography Ramon Margalef. This boat also permitted to use biological, chemical and physical, but his greatest contribution is to put images to this eruptive process and, finally, to directly observe what is happening underwater El Hierro. This is achieved with an underwater robot of last generation, equipped with a powerful lighting and several cameras.

Steam explosions

The type of eruption is happening in El Hierro can lead to large steam explosions, and even the island to expand their territory with areas of lava emerged, explains Jos? Luis Fern?ndez-Turiel, a geologist at the Institute of Sciences Jaume Almera Earth and expert in the Canary volcanism.

The eruption could cause the island to expand its territory

The emergence of a new ground together with the island was precisely what happened during a submarine eruption on the island of Faial in the Azores, much like the El Hierro. Between 16 and September 27, 1957, 200 earthquakes were recorded. Shortly after, the sea began to boil, there were tremors and eruptions began appearing steam and ash. "There were two eruptions that were approaching land," says Fern?ndez-Turiel, who stresses that, in this case, the depth to which was the starting point of magma ocean was less than 100 meters. According to recent data, the eruption of El Hierro is at depths of between 600 and 150 meters.

In these cases where there are eruptions in shallow water, magma, which is "about 1,200 degrees, turns water into steam very quickly," says Fern?ndez-Turiel. That contact expands the volume of water "1,600 times," causing explosions. The eruption in Faial, which lasted until 1958, destroyed 300 homes and caused the evacuation of about 2,000 people, many of which migrated to the U.S. and Canada. After the volcanic process, the island had gained about 2.5 square kilometers.

The volcanologists call this type of phenomena surtseyanas eruptions, by the name of the island of Surtsey, which emerged in 1963 off the southern coast of Iceland after another eruption. This happened to 130 meters and lasted four years.

"It is difficult for the eruption of El Hierro last, because it seems small, in this sense, it resembles the scene of Surtsey," says Fern?ndez-Turiel, however, warns that there is no way to predict in detail how it will evolve the eruption.

The ship can measure up to 1,500 meters deep

"Every volcano is different and behaves according to its own rules, so you do not understand anything he says as follows," warns Ryan Portner, a researcher at the Research Institute Aquarium, Monterey Bay, California. Underwater eruptions are more frequent than on land, are also much more difficult to detect and study, especially those that occur in remote and deep waters. Portner points out that there are three methods to do so. The first is a network of sensors on the seabed, which does not exist in El Hierro. The second is to use a submersible robot guy who will travel on Monday. The third is the detection of "hot sea water with a strange chemistry," says Portner. In the case of El Hierro, in the early days the authorities concluded that a rash had a light green stain due to the chemical elements that contain the magma, and dead fish. Portner believes that they are "good indicators", but that could also be due "to a hydrothermal process not associated with volcanism." According to the researcher, it is necessary to sample and find the spot to confirm that magmatic particles have been rash.

Discard one or the other source is one of the "most difficult challenges when eruptions occur how are you," said Robert Tilling, USGS volcanologist U.S.. Hydrothermal vents are vents on the seafloor by leaving water and chemicals at high temperatures. Occur in volcanic areas where the magma is mint on the surface. Thousands of earthquakes in El Hierro are not worth to rule out either option, Tilling says, since both "may be associated with earthquakes."

El Hierro volcano magma check, close access to area

Saturday October 15, 2011 16:32 EST

MADRID (Reuters) - The submarine volcano El Hierro is ejecting magma and the authorities have blocked access to the nearby town of La Restinga and has banned helicopter flights over the area, reported on Saturday Cabildo de El Hierro in his Twitter account.

"Due to the occurrence of pyroclastic steaming at sea, closed to the restricted access until further notice," said one tweet after three in the afternoon.

The research vessel "Professor Ignacio Lozano" who was in the area has returned to port as a precaution.

It is envisaged that an hour is given a scientific assessment on the new stage.

The authorities of El Hierro (10,000 inhabitants) on Monday confirmed a volcanic eruption in the Canary Island waters after living hundreds of tremors in recent weeks. Volcanic eruption is the first in Spain since 1971.

On Tuesday he ordered the evacuation of the population of 600 residents of La Restinga in the south of the island, located about 5 km from the eruption, which could be between 600 and 1,000 meters deep.

In recent days has appeared a greenish stain on the water now seemed closer to the coast.

IGN-CSIC scientists claim that evolution of the volcanic eruption may have four phases

15/10/2011 ... 20:28 - Ministry of Economy, Finance and Security

The culmination of all of them depend on the amount of magma expelled

Scientists at the National Geographic Institute (IGN) and the Centro Superior de Investigaciones Cient?ficas (CSIC), have confirmed, in the afternoon today, the eruptive process of El Hierro is a surtseyana like rash, consisting of four phases. However, they said that the completion of these depend on the amount of magma expelled by the volcano.

As explained by the coordinator of the team of scientists from CSIC, Ramon Ortiz, the first phase, the effects have been seen today, is the expulsion of "lava bubbles that carry gas and once they lose sink." In a second stage, according to Ortiz, "you will see a white column of steam" that will give way to the third phase to be observed "black colored explosions known as rooster tails." Finally, you can view "the growth of a small island where a fountain of lava flow type pump".

Ramon Ortiz also said that the diameter of the mouth of the volcano should be about one meter in diameter and it has caused a strain on the island of about five centimeters. He said that the eruption will be visible when you are 60 meters deep.

As you may recall, the Canary Islands Government raised this morning to the emergency red light, Level 1, in which, in addition to the mandatory evacuations, mobilized the necessary resources for intervention activities and logistics. This was transmitted PEVOLCA address to the people of La Restinga, which must follow closely the recommendations of the authorities and members of civil protection.

For his part, Director General of Security and Emergency, Juan Manuel Santana, announced that tomorrow will be another meeting of the Steering Committee PEVOLCA, which was attended by President of the Government, Paulino Rivero, and the director and adviser Plan Economy, Finance and Security, Javier Ortiz. The meeting will take place at 13:00 pm in the City of El Pinar.

The residents of La Restinga could return to their homes in the next 24 hours

16/10/2011 ... 16:25 - Ministry of Economy, Finance and Security

The tunnel Roquille in Frontera, could open in the same period of time

President of the Canary Islands, Paulino Rivero, announced this morning that the residents of La Restinga could return to their homes in the next 24 hours. In the same period of time could also open tunnels Roquille in the town of Frontera.

This decision is based on reducing the level of seismicity that scientists have detected and parameters observed in the evolution of the eruptive process. In this sense, it was determined that there is no danger to the public on the current situation and that this could be extended in time from days to months.

In any case, the Prime Minister stressed that the return home of the inhabitants of La Restinga will be taking important precautions and extreme vigilance day and night, so that any change in the development of the phenomenon, allowing the realization of rapid evacuation, as was held on Tuesday, January 11.

Note that the teaching of the classes will remain in El Pinar, will not be allowed to return home for bedridden people and to remain permanently transport in La Restinga.

The Chairman also announced the installation of several hydrophones in the spring of La Restinga, by Jaume Almera Institute (CSIC). This equipment will allow the position to know which is the central issue, and the direction of the crack, and could detect if it were to produce the appearance of a new source of emission.

On the other hand, the Prime Minister said that turning down the level of seismic intensity and placing a mesh estarse protection in tunnels Roquille reduces the risk of landslides. Therefore the Executive is planning to open the tunnel to traffic within 24 hours "under control measures, security and surveillance extreme".

Regarding navigation, Rivero reiterated that maintaining the exclusion zone but allow fishermen to move their boats to the port of La stake for them to continue fishing.

Finally Rivero stressed the exemplary behavior of the population of El Hierro and especially the residents of La Restinga, and confirmed that it would take a package of measures aimed at individuals, freelancers and small businesses who have been affected by the consequences of this phenomenon .

The evolution of the eruptive process in the last 24 hours to deferring the return of residents to La Restinga

17/10/2011 ... 22:04 - Ministry of Economy, Finance and Security

The neighbors will be informed tomorrow at 16 am at the Cultural Center of El Pinar, on the possibility of returning to their homes

The evolution in the last 24 hours eruptive process that develops near the coast of La Restinga, has forced the leadership of Civil Protection Plan for Volcanic Risk (PEVOLCA), to postpone the return of residents to their homes, to to conduct an analysis of environmental quality.

The appearance of the stain in the same dock and the perception of certain odors do this test have been advised to discard any toxicity "very unlikely indeed."

In this sense, the direction of PEVOLCA will meet with all the neighbors in the Cultural Center of El Pinar to pass on the results and assess the possibilities of returning to their homes.

On the other hand, Juan Manuel Santana announced that tomorrow will proceed to the partial reopening of the tunnels Roquille in Frontera, keeping it a permanent monitoring service. The Director General of Security and Emergency said that, from eight o'clock to eight o'clock in the afternoon, only allow the movement of goods vehicles exceeding a tare weight of 3,500 kilograms, transportation of dangerous goods and safety and emergency in service.

The reasons that have led to making this decision have been, according to Santana, "the decreased levels of seismicity, as well as cleaning the catchment by the City Council of El Hierro, and placement of the backstop," he which makes it appropriate conditions for this partial reopening. Regarding the rest of the circulation, the Director General of Security said that decisions taken in this regard will go progressively according to the evolution of the eruptive process.

Regarding the relocation of the residents evacuated in Frontera, the Director General of Security and Emergency, Juan Manuel Santana, announced that, after inspection of the eleven houses affected "only authorize the return of the inhabitants of four to be located outside the dejection cones and have other previous dwellings that can serve as a parapet in case of landslides occur. "

Sample Collection
Referring to the Oceanographic Vessel Prof. Ignacio Lozano, the Canary Islands Institute of Marine Science, this ship has gathered today in large amount of pyroclastic material and biosolids found on the surface.

Furthermore, hydrological sampling was performed multiparameter probe with sampling water biogeochemical characterization (temperature, salinity, pH, chlorophyll, turbidity, dissolved oxygen, gases and nutrients) of the area, continuously monitoring the concentrations of vapor H2O, CO2, H2S, SO2 and HCl in ambient air, and underwater noise characterization using hydrophones and whale watching.

These works have been carried out by specialists from the Canary Islands Oceanic Platform, the Spanish Institute of Oceanography, Institute of Technology and Renewable Energies (ITER) and the University of La Laguna.

El Hierro fears another eruption


Rosa Rodriguez / Santa Cruz de Tenerife
25/10/2011 Actualizada a las 12:19

The scientific community is confused with the recent geological events in El Hierro. What answers do not understand the increase in seismicity in Frontera last weekend and fears a repeat of the process that caused the eruption of October 11 in front of La Restinga.

The first puzzled us because we can not guarantee what's happening in El Hierro. Under the sea do not see it. " Joan Mart?, who heads the group of active volcanology of the Higher Council for Scientific Research (CSIC), which is advising the National Geographic Institute (IGN) in the volcanic crisis of El Hierro, the scientific community admits that "do not know yet" how explain that while the eruption of La Restinga seems to be coming to an end, it produces a spike of seismicity in Frontera, roughly the same area of ​​the initial current eruptive process.

The only clear that they have both the CSIC researchers and technicians from IGN is that the seismicity "has disappeared in the south" of El Hierro, the volcanic tremor behaves as expected and that the ground deformation has ceased, symptoms that "the phase of explosive risks have passed away" in La Restinga, but "this is not over," says Joan Marti.

In the coming days, experts will study the seismicity "to see how it behaves and if at any time is associated with a new strain, suggesting new pressure in the system," said lead researcher of the CSIC, which does not rule out a new volcanic process elsewhere on the island or, more likely, in the sea, again in front of La Restinga.

The seismicity of these days when Frontier is following the same patterns that led to the submarine eruption of October 11, and "although there is recorded a little further east, is in the same north-south line," says Marti .
It is also not rule out that the hundreds of earthquakes that have occurred this weekend have Border non-volcanic and tectonic origin. Point so much as Joan Mart? IGN director in the Canaries, Jos? Mar?a Blanco.

The explanation given is that, despite the similarities with the records of the months prior to the eruption of La Restinga, this time the earthquakes are occurring at a depth ranging from 20 to 25 kilometers and also " are not associated with the deformation of the ground as it did then. " The tectonic origin of these earthquakes could respond to a settlement of the fracture zone that slipped by the magma, "a readjustment of the whole system," says Marti. If your source is volcanic can tell "if there is more magma is moving down and up" because with the eruption of La Restinga "pressure has been removed volcano of El Hierro," he adds.

The submarine volcano El Hierro has formed a cone of lava hectometres 12 in two weeks
...

ALICIA RIVERA - New York - 26/10/2011

The submarine volcanic cone of El Hierro has a volume of 12 cubic hectometres (equivalent to approximately a dozen great football stadiums integers) and the tongue of lava, which extends for several kilometers, has two hectometres as data taken in the last hour of the research vessel equipment Ramon Margalef, who has moved to the waters of El Hierro in his first season of research. "This volume of lava in just 15 days is quite remarkable, since the eruption began on October 9," said Juan Acosta El Pais, a geologist and head of the campaign on board the Ramon Margalef.

The volcano continues, is generated at the tip of a crack. Scientists have made the ship preliminary analysis of the data, which are discussed in detail below.

The new volcanic cone, 300 meters deep, has a base diameter of 700 meters, a height of 100 meters and a crater about 120 meters. The lava on the sea floor solidifies, forming a crust on the surface, but underneath is still sticky, but eventually solidifying all, Acosta said by telephone from the ship.

Scientists are on board the Ramon Margalef are entrusted with the task of taking all possible information and delivering it to Pevolca (Civil Protection Special Plan and Emergency Response for Volcanic Risk in the Canary Islands), namely the Scientific Committee, which directs the National Geographic Institute.

The first phase of the campaign for this new ship of the Spanish Institute of Oceanography sent to El Hierro has resulted in the complete mapping of the seabed in the affected area, carried out with the echo sounders on board, says Acosta, and the boat is now in Stakes port waiting for the four technicians who have to embark on the next few hours to prepare the submarine Liropus. Experts try to observe the volcano underwater video cameras high resolution of the submarine. In addition, a sled is also used camera. Lead the second phase of the campaign Francisco Sanchez, and then from October 31, will be held the third phase to the physical and chemical characterization of the water column.

The Liropus is directed from the Ramon Margalef, which is linked by a fiber optic umbilical cable. It weighs 800 kilos and descends to the water within a structure, like a cage, then released and begins his solo sailing distances to 250 meters from the cage to which it remains attached by a wire, optical fiber is also very lightweight. The camera sled, however, does not sail by itself, but is dragged by the ship. In addition to various chambers, the submarine has two articulated arms of sampling and a suction pump. You can reach 2,000 meters. The submarine, purchased from a Scottish firm, has cost 1.5 million euros, is the first in Spain with a capacity to reach these depths and its essential purpose is the study of marine protected areas, said Jose Ignacio Diaz, head of IEO fleet.

Both the submarine submerged as the lead sled lights to illuminate the environment and to grasp with their cameras, as in the water, from one hundred feet deep, total darkness, explains Acosta. The two teams will move near the bottom, two to six meters.

The Ramon Margalef, commanded by Captain Luis Gago, arrived in El Hierro on Sunday and two days later, scientists and technicians on board and had located the crater of the volcano and raised a first mapping of the seabed in the area. To do this, we used high-resolution echo sounders which bears the ship. This is equipment that uses sound waves at different frequencies and capture default sound bounce, so that we can reconstruct the background. For proper operation of this equipment is essential a very important feature of Ramon Margalef: It is very quiet.

The ship, which cost 18 million euros, carries 12 crew members and 14 researchers and technicians in this first scientific campaign. Its performance is still very good and responsible IEO are satisfied. Even the experts working on board include the proper functioning of the ship and its equipment. "It's an ideal ship for this type of work and also we are doing at the time also ideal, because with the active eruption could not have surf-for security reasons," said Acosta.

IGN confirms an earthquake of magnitude 3.9 to 22 km depth northwest of Frontier

30/10/2011 ... 10:42 - Ministry of Economy, Finance and Security

He felt as Valverde and Frontera CECOES 1-1-2 calls

The National Geographic Institute has confirmed this morning the direction of the Civil Protection Plan for Volcanic Risk (PEVOLCA) an earthquake of 3.9 magnitude, northwest of Frontera, located in the sea to 22 miles deep. The quake, which was felt by the population, occurred at 7:46 pm and is the largest earthquake recorded in the island after the onset of the eruption south of La Restinga.

The 1-1-2 CECOES received calls from the towns of Isora, Guarazoca, Mocanal (Valverde) and Tigaday (Border)

The evolution of seismicity in the north of the island has increased in recent days and scientists who are monitoring constantly shuffled all possible scenarios, but still can not be defined with sufficient precision. In this sense incline between the main options that the process reduces or evolve into a rash located, most likely, at sea, with the features being developed to the south, whose parameters are stable.

Moreover, those responsible for the IGN confirm that during the day yesterday, October 29, 62 earthquakes were located, two of which were felt by the population. The earthquake of greatest magnitude reached a value of 3.6 on the Richter scale. This movement has been located at sea in the Gulf area about 4 miles from the coast at a depth of 23 km has been felt by the population with maximum intensity IV in the town of Valverde.

Most of the other registered events are located in the same area, aligned NNW SSE from the sea, about 12 kilometers from the coast to the center of the island. The depths vary between 15 km and 25 km.

In total, since the day July 17, 2011 10 615 events have been found.

Deformation
According to reports from scientists at the University of Cadiz, and with reference to the deformation of the ground, continue two separate scenarios. The south of the island shows a remission in increasing deformation, clearly marked by the eruption process and that is evident in the data recorded in the GPS station of La Restinga.
In the north of the island, seen in the deformation component increased to a lesser extent North and the East.

Spot
Throughout the day have been observed clearly the main emission areas in which it has been seen fragments of lava. Also during the October 29 confirms that the stain has already spread to the entire Gulf area

Re: Canary Islands Government Raises El Hierro Volcanic Risk Level - PEVOLCA confirms subsea eruption - Red Alert issued for La Restinga

Translation(Google)

El Hierro is suffering the largest earthquake in the seismic crisis
CO2 emissions on the island is at the highest levels since the first eruption heralded

BERNARDO MARIN | Madrid 02/11/2011

The volcanic phenomenon in El Hierro is reactivated and new indications predict an eruption, this time in the north in the Gulf area. In fact they are repeating almost millimeter some signs that presaged the first, which began on October 10. The island has suffered todayThe largest earthquake seismic crisis. IGN page 1910 recorded an earthquake measuring 4.4 on the north, where earthquakes are concentrated lately. The previous two were stronger than 4.3, one this morning and the day before the eruption. Furthermore, levels of carbon dioxide (CO2), a gas that accompanies eruptive processes in the past has reached its highest level measurements on the island since the crisis began, even higher than recorded in the days before the emergence of lava under the sea off the coast of La Restinga.

CO2 is vital for the monitoring of these phenomena and which is the second major component of volcanic gases after water vapor, and because of its low solubility in the magma can easily escape to the surface. Pedro Hernandez, a researcher at the Institute of the Canary Islands volcanological (non-tip), explains that "the average of the diffuse emission of CO" on the volcano island of El Hierro is about 340 tons a day. And the last measurement reflects more than 1,000. "Specifically 1044 tons (+ - 31), compared to 990 (+ - 49) measures the days before the first eruption. To control these emissions have selected some 600 non-tip measurement points throughout the island.

The increase in CO2 emissions in itself presents no problem of toxicity to the population. "In the Parque del Retiro or say in a rainforest diffuse flow values ​​are measured CO2 in the soil can be higher than those being measured in the surface environment of El Hierro," says Hernandez. The point is that the total count of these emissions has increased significantly, indicating a greater contribution to endogenous (deep) to the desgaificaci?n. "There is a revival, that's for sure, a new injection of magma are looking for a way out, now the north, and that is causing the earthquakes," says Hernandez, "and there will be an eruption if the magma has enough energy to break and find where to escape. "

The fact has not yet occurred and that it occurred on the eve of the eruption of La Restinga what volcanologists call a "migration towards more shallow seismicity," meaning shallow earthquakes. So far, in recent days there have been between 15 and 30 kilometers deep, but one this morning to only 9. According Pevolca said, crisis management agency, on Monday a stage "with eruptions at 10-15 miles if could be valued as a precursor to an eruption."

On the eve of the first exit of magma several earthquakes occurred just 1 or 2 kilometers deep. Thus today some warning has been unleashed on social networks in which the population of El Hierro overturned lives these days, after two earthquakes measured at 3 and 1 km deep. The Pevolca then issued a note to remember that both had occurred far away from the area where seismicity is concentrated at very low magnitude and the depth was subject to revision. In fact a few minutes later both appeared earthquakes located 22 kilometers deep and 9, respectively.

Restinga is evacuated
Rosa Rodr?guez / EFE / Border

Late this afternoon, just before sunset, has intensified the submarine eruption. The bubbling was leaning on the surface. The bubble has risen to a height similar to a two-storey building and has risen as a result of gassing.

Many neighbors have witnessed the phenomenon, and even applauded.

The Security and Emergency Councillor of the City of El Pinar has confirmed the decision to move to the village of La Restinga, which should leave their homes for the second time since the crisis began.

Within half an hour has evacuated La Restinga in cars and buses in the Emergency Military Unit. As the neighbors again who do not have to stay, they will in the school residence Valverde.

The direction of 8informa PEVOLCA a press release has been ordered to evacuate as a precaution La Restinga. This decision was taken in observing changes in the eruptive phenomenon, as has been seen with ash plumes in the area, he adds.

Besides the Roquille tunnel, this Saturday it was decided to close five highways in El Hierro due to the increase in earthquakes can cause landslides on the slopes.

The risk has not changed over days for the population, as recently reported following the meeting of PEVOLCA on Saturday. The spot is larger, more intense bubbling and pyroclastic also increased in size.

According to EFE, the press conference after the meetings of committees of Pevolca scientist and the Director General of Security and Emergency of the Canary Islands, Juan Manuel Santana, said the situation has not changed in terms of population, whereas before the risk of further landslides on some slopes has decided to take action.

Juan Manuel Santana said no more evacuations are planned after this Friday will carry out that action in eleven houses in the neighborhood of the tips, in the town of Frontera, after registering an earthquake of magnitude 4.4 on the scale of Richter.

The increase in the magnitude of earthquakes increases the risk of occurrence of landslides, said Juan Manuel Santana, who acknowledged that the measures adopted Saturday by the Pevolca are annoying to the citizens of the island.

In addition to the closure of tunnels Roquille the Pevolca has agreed to close the road from the tips, which is near the exit of the tunnel through the town of Frontera, from the junction of the cross roads to the Well of Patterns.

Also closed and the Lizard Ecomuseum and HI-500 road between the lighthouse and the Well Orchilla Health and Sabinosa area cut the road to Frontera, at various points, and access is prohibited the well of the decals.

To complement these measures will be roadblocks Civil Protection and Security on the road to the summit and on the roads of The Well of Health and Las Tablas.

Juan Manuel Santana said the Pevolca is scheduled to meet until Monday, to follow the evolution of volcanic seismic phenomenon, and insisted that what is intended is to prevent the risk.

There is a risk that the slopes of risk exposures due to increased seismicity and what is intended with the action taken is to prevent people from damage, said Juan Manuel Santana.

The director of the National Geographic Institute (IGN) in the Canary Islands, Jos? Mar?a Blanco, said the earthquake of 4.4 magnitude on the Richter scale of etse Friday was more felt by the population above the same magnitude as occurred in a place closer to the coast.

The place where the earthquake was detected of 4.4 magnitude yesterday is an oceanic continental crust from the previous of the same magnitude, so that transmission power is greater and therefore the acceleration with which felt, said Maria Jose Blanco.

The director of the National Geographic Institute in Canary also said that from a boat for the marine reserve of the Calm Sea have been collected solid samples during the last hours underwater volcanic eruption has left the area of ​​La Restinga, in the south of the island.

Maria Jose Blanco said that the magnitude of earthquakes could come in the coming days to magnitudes of 4.5 or 4.6 degrees on the Richter scale.

El INVOLCAN confirms a further increase in carbon dioxide emissions in El Hierro

11/06/2011 ... 20:06 - Ministry of Economy, Finance and Security

The new results show an emission of 1218 ? 46 tonnes per day

The volcanological Institute of the Canaries (non-tip) confirmed the direction of the Civil Protection Plan for Volcanic Risk (PEVOLCA) a further increase in the diffuse emission of carbon dioxide (CO2) into the atmosphere by the volcano island of El Hierro. The measured emission rate has reached 1218 ? 46 tons per day, the highest value observed since the beginning of magmatic reactivation being recorded in El Hierro.

Since last July 21, 2011 the non-tip 7250 has materialized over diffuse flux measurements of carbon dioxide (CO2) through numerous scientific investigations carried out throughout the building subaerial volcanic island of El Hierro (278 km2), and in which they have collaborated and collaborate a significant group of volunteers based in the Canary Islands. The scientific purpose of these campaigns is to contribute to the improvement and optimization of monitoring volcanic gases as are the driving force of volcanic eruptions.

The registration of the diffuse emission of carbon dioxide (CO2) by the volcano island of El Hierro from July 21 to date ranges from 331 to 1218 ? 16 ? 46 tonnes per day. Following the work of diffuse emission of carbon dioxide (CO2) made by the group El Hierro volcanological ITER since 1997, now within the non-tip, has been established that the average value of the diffuse emission dioxide (CO2) by the volcano island of El Hierro is 345 tons per day. On October 6, 2011 and prior to the submarine eruption occurred southwest of La Restinga diffuse emission rate of carbon dioxide (CO2) reached 990 ? 49 tons per day, an emission rate 2.8 times higher than average normal. Recent results show that the emission rate is about 3.5 times the normal average.

The Directorate of Civil Protection Special Plan and Emergency Response for Volcanic Risk in the Canary Islands (PEVOLCA) points out that the diffuse emission of CO2 is one of the parameters of a volcanic eruption precursors but has to be assessed in conjunction with other such as deformation, and seismicity depth. It should be remembered that we are immersed in an eruptive process underway in the south of the island, which generates greenhouse gas emissions in the Earth's surface.

The management also strongly encourage people across the island to focus their attention on the messages offered by the competent authorities which assists the Scientific Committee. Public authorities have the devices and means to cope with a change in the current situation with the media, at the right time, precise instructions for the population.

In early November, a submarine volcano continued to spill gas and volcanic debris into the Atlantic Ocean south of El Hierro, in the Canary Islands as earthquakes rocked the land northwest of the Island. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA?s Aqua satellite captured this true-color image of the milky, yellow-green stained sea south of the island on November 2, 2011. On that same day, a magnitude 4.4 earthquake was reported in El Golfo Bay, a half-moon bay on the northern side of the island. The earthquake was followed by a strong harmonic tremor.
Tremors first began on the Island of El Hierro in July, becoming more frequent and stronger until early October, when the underwater eruption began. Reports from a recent underwater survey revealed an eruptive vent and crater about 150 meters (500 feet) below the surface, along with submarine ?pillow? lava ? a pillow-shaped lava that forms underwater. By November 3, there were reports of increased bubbling of the water above the eruption site, a phenomenon that some locals are calling a ?jacuzzi?. On November 4, earthquakes increased, with 15 tremors of a magnitude 1.5 or greater reported between midnight at 8:30 UTC, and more during the rest of the day. On November 5, residents of La Restinga, a town about 7 kilometers north of the volcanic vent, were evacuated due to the increased activity in the area.

Volcanologists INSTITUTE OF CANARIES
Scientists at the Institute of Technology and Renewable Energies (ITER), an agency of the Cabildo of Tenerife, and is now part of volcanological Institute of the Canaries (non-tip) - an institution demanded unanimously by the Senate (2005), Canary Islands Parliament (2006) and House of Representatives (2009) with the aim of contributing to improving and optimizing the management of volcanic risk in Spain - have confirmed the direction of the Civil Protection Special Plan for volcanic Risk in the Canary Islands (PEVOLCA) detection of the largest temperature anomalies associated with the most obvious surface manifestation of the underwater eruption being recorded south of La Restinga.

The difference in temperature at the surface marine environment south of La Restinga using thermal imaging cameras in air mobile position is the largest detected so far, more than 11 ? C. Water temperature in the surface environment of the Calm Sea that is not intensely affected by the eruptive activity was 23.9 ? C, while recording the water temperature in the area where we observe the most obvious surface manifestation the underwater eruption reaches the 35.3 ? C. This temperature difference in the surface environment of the Calm Sea clearly reflects a major heat flow as a result of submarine eruption.

The measurements have been made ​​on Sunday November 6th through the support and cooperation of the Service Civil Guard helicopters as part of a collaboration between the non-tip and the airline industry in the Canary Islands Civil Guard to strengthen the geophysical program (thermometry and thermography) that provides non-tip for volcano monitoring in the Canaries.

Intensify the explosions in El Hierro
A column of ash, rocks and gases emerge from the bubble in the Sea of calms and rises above twenty feet above the sea level. The explosion has left a strong smell of sulfur in La Restinga. On 17.00, a new explosion has caused the magmatic material rises about 10 meters

PEDRO WAR / LAPROVINCIA.ES explosions were intensified in the Sea of ​​Calm. Around 1610 hours on Tuesday an explosion of ash, rocks and gases bubble that emerged throughout the morning has been active in the Sea of ​​calms. Possibly, this explosion is the largest seen so far in the underwater volcano near La Restinga and that could have been elevated above sea level more than 20 meters.

The explosion left a strong smell of sulfur in La Restinga.

A second explosion took place at 17.07 hours. Has occurred in the Sea of calms and magmatic material has risen about 10 meters high.

During this Tuesday also have thousands of dead fish appeared in La Restinga.

Prohibit access to two coves in El Hierro gas risk


Benedict Luigi Borges (special envoy) | Frontier (El Hierro)

Updated Wednesday 11/09/2011 19:22 horasDisminuye textoAumenta size textoLas size Tacor?n coves and Puerto Naos, south of the island of Hierro have been closed to the public. Civil Protection Plan for Volcanic Risk Islands (Pevolca) has taken the decision after receiving the relevant scientific advice. These studies have found that the sea current and wind could push them to the fumes emitted by the eruption and, given the morphology of the same, they could be accumulated in the creeks and be harmful to the health of the population.

On what there is no variation on the situation of the people evacuated from La Restinga, where people can still access it from 8:00 to 18:00. This location is located in a more open and airy space that Tacor?n coves and Puerto Naos, so it is possible that may occur on its shores a buildup of toxic gases.

In this regard, the Director General of Security and Emergency Pevolca Canary Islands and the Juan Manuel Santana, the coach has clarified that the National Geographic Institute (IGN) that on Tuesday felt unwell while performing measurements of carbon monoxide in the south Iron is found in perfect condition. The parameters of his team revealed that there had been no measurements harmful to humans, so it is possible that his discomfort was motivated by an allergic reaction.

However, the Public Health Department continues to analyze the air quality in the area 24 hours a day. Similarly, the analysis conducted by the Canary Islands Health Service with respect to the dead fish that keep popping up in the port of La Restinga and other surrounding areas indicate that these have been killed by depressurization and lack of oxygen, not having taken metals or toxic substances expelled by the volcano.

Santana also clarified that remain active security measures taken last Saturday, which include the closure of several roads and the Roquille tunnel, and it is still likely that some of the earthquakes that are felt daily in Frontera reach magnitude 4.6 on the Richter scale.

In this sense, the director of IGN in the Canaries, Jos? Mar?a Blanco, did not rule out continuing aftershocks could lead to a future in another submarine eruption in the north of the island, although this would occur at great depth.

On the southern eruption, scientists continue to run various scenarios, including an explosive eruption that turn into reaction by washing with water. This volcanic cone should continue to grow to be at least 150 meters deep, a fact that is still far from happening.

"A volcano is created in 18 days with a height of 100 meters, but in order to grow and become unstable, it must broaden its base. And that requires an injection of much larger cubic meters. That is, As the building is higher, its growth is slower, "said Blanco.

Moreover, the City Council of El Hierro and Telefonica have agreed to for anyone who wishes to make a direct monitoring eruptive phenomena on the Internet.

One of the cameras focus at La Restinga and the Sea of ​​Calm in a pan, while the second will focus on the focus of the underwater volcanic eruption, which is now apparent 'bubbling'.

Telef?nica has had to enable a special server to hold the hypothetical massive demand for images. The placement of cameras in the area had been claimed by several hundred Internet users who even signed petitions to send to the City Council, but the project was delayed by the technical conditions presented by the fishing village of La Restinga. According to council sources, it is expected that the two 'webcams' to be operational shortly.

The volcano of El Hierro is one month old

Nobody can predict the evolution of process .- In case, the IGN and make plans for Christmas

EMILIO DE BENITO - Valverde - 10/11/2011

A month ago mouths were detected underwater volcano of El Hierro. It was the natural outlet of the magma was pressured by the earthquakes that shook the island since July. Since then, the island population of about 11,000 inhabitants live pending the whims of a process that is characterized by two aspects: in general, as business to repeat every time you ask the director of the National Geographic Institute ( IGN) in the Canary Islands, Jos? Mar?a Blanco, "within expectations". But day by day, full of uncertainties. This is a summary of what is known and what is not.

Current situation. The phenomenon is now divided: the north of the island's earthquakes occur on the south, the volcano, or volcanoes, as they have counted to three mouths, but there is one closest to the coast - about 1,800 meters, which is what accounts for the observations of neighbors, reporters and onlookers.

Effect on the population. There are about 650 people evacuated. The majority of the approximately 600 residents of La Restinga in the south of the island, which can only go to town day (from 08.00 to 18.00). But there are 51 other leading north a week away from their homes by the earthquake risk to cause landslides.

Infrastructures. In the north is cut Roquille The tunnel, which connects the island's capital, Valverde, and the main economic, El Golfo, whose capital is Frontera. The population difference is that a good road trip of 10 minutes has become a 45 for a mountain road. Apart from that there are half a dozen other traffic courts in the north. In the south, apart from limited access to La Restinga, is banned from entering Tacor?n and Puerto Naos, for fear of the gases.

Personal injury. So far, there has been. It has only been necessary to address possible poisoning by gas-TBC-IGN to an investigator. There is no anxiety and disorders of the displaced population, which led to some of their representatives to request the assistance of psychologists.

Economic damage. There is a calculation, but La Restinga, who lived by fishing and diving, takes a month of inactivity. The authorities are considering measures such as tax exemptions or credits that do not meet ICO those affected, who want individual plans.

Intensity of the phenomenon. So far, the tremors have remained within expectations: a maximum of 4.4 (expected up to 4.6). There have been more than 10,000 smaller earthquakes. Rare is the day that people do not feel one (the threshold for notice is about magnitude 3). Today has been, so far, very few (a dozen), all minors.

Emissions from the volcano. South of the island is a huge stain on the sea of ​​lava and dissolved gases. Marine life has disappeared in the area, and it is not uncommon to see dead fish. Analysis indicates that due to two phenomena: the lack of oxygen in the water and depressurization accompanying eruptions. Not detected high concentrations of heavy metals, which is good news.

Gases. Apart from the bubbles that occasionally crop up, is the phenomenon of greatest concern to the authorities at this time, because they may affect the health of the inhabitants of La Restinga. Occasionally detected an odor of rotten eggs or sink (sulfur), but there are also concentrations of CO2 and CO, which are those that have been preventing access to some beaches. SO2, which produce acid rain, is diluted in seawater.

Will there be a volcano? There are three possibilities. The most likely, in the south. This already exists, but as it is formed in a marine valley, it seems unlikely to emerge. It is possible that there mouths in the north (also offshore) or even very remotely, on the mainland.

Duration of the process. It's the million dollar question. On average, Canary eruptions have lasted a month, says White. This period has been fulfilled, and the issue seems to go for long. IGN is already making plans to meet its monitoring at Christmas. The same, but more of a joke that was what the vulcanologist said Tuesday Ruben Lopez, when he declared that he was making plans with civil guards posted to the area for year-end celebration.
