http://en.wikipedia.org/wiki/File:Iceland-from-space.png

Vatnaj?kull (English: Glacier of lakes) (IPA: [ˈvaʰtnaˌj?ːkʏtl̥][dubious ? discuss]) is the largest glacier in Iceland. It is located in the south-east of the island, covering more than 8% of the country. With an area of 8,100 km?, it is the largest ice cap in Europe by volume (3,100 km?) and the second largest (after Austfonna on Nordaustlandet, Svalbard) in area (not counting the still larger ice cap of Severny Island of Novaya Zemlya, Russia, which may be regarded as located in the extreme northeast of Europe). Greenland (and Antarctica) are ice sheets. On 7 June 2008, it became a part of the Vatnaj?kull National Park.[1]

The average thickness of the ice is thus 400 m, with a maximum thickness of 1,000 m. Iceland's highest peak, Hvannadalshn?kur (2,109.6 m), is located in the southern periphery of Vatnaj?kull, near Skaftafell National Park.

Under the ice cap, as under many of the glaciers of Iceland, there are several volcanoes. The volcanic lakes, Gr?msv?tn for example, were the sources of a large j?kulhlaup (glacial lake outburst flood) in 1996. There was also a considerable but short-time eruption of the volcano under these lakes at the beginning of November 2004. During the last ice age, numerous volcanic eruptions occurred under Vatnaj?kull, creating many subglacial eruptions. These eruptions formed tuyas, such as Her?ubrei? which was beneath Vatnaj?kull during the last ice age.

Most of these small earthquakes are located on the north west side of the glacier. They might not be of any significance, but any cluster is interesting to note.

</TD></TR><TR><TD class=vxRemarks colSpan=4>The large central volcano of Bárdarbunga lies beneath the NW part of the Vatnajökull icecap, NW of Grímsvötn volcano, and contains a subglacial 700-m-deep caldera. Related fissure systems include the Veidivötn and Trollagigar fissures, which extend about 100 km SW to near Torfajökull volcano and 50 km NE to near Askja volcano, respectively. Voluminous fissure eruptions, including one at Thjorsarhraun, which produced the largest known Holocene lava flow on Earth with a volume of more than 21 cu km, have occurred throughout the Holocene into historical time from the Veidivötn fissure system. The last major eruption of Veidivötn, in 1477, also produced a large tephra deposit. The subglacial Loki-Fögrufjöll volcanic system located SW of Bárdarbunga volcano is also part of the Bárdarbunga volcanic system and contains two subglacial ridges extending from the largely subglacial Hamarinn central volcano; the Loki ridge trends to the NE and the Fögrufjöll ridge to the SW. Jökulhlaups (glacier-outburst floods) from eruptions at Bárdarbunga potentially affect drainages in all directions.

</TD></TR><TR><TD class=vxRemarks colSpan=4>Grímsvötn, Iceland's most frequently active volcano in historical time, lies largely beneath the vast Vatnajökull icecap. The caldera lake is covered by a 200-m-thick ice shelf, and only the southern rim of the 6 x 8 km caldera is exposed. The geothermal area in the caldera causes frequent jökulhlaups (glacier outburst floods) when melting raises the water level high enough to lift its ice dam. Long NE-SW-trending fissure systems extend from the central volcano. The most prominent of these is the noted Laki (Skaftar) fissure, which extends to the SW and produced the world's largest known historical lava flow during an eruption in 1783. The 15-cu-km basaltic Laki lavas were erupted over a 7-month period from a 27-km-long fissure system. Extensive crop damage and livestock losses caused a severe famine that resulted in the loss of one-fifth of the population of Iceland.

</TD></TR><TR><TD class=vxRemarks colSpan=4>Askja is a large basaltic central volcano that forms the Dyngjufjöll massif. It is truncated by three overlapping calderas, the largest of which is 8 km wide and may have been produced primarily from subglacial ring-fracture eruptions rather than by subsidence. A major rhyolitic explosive eruption from Dyngjufjöll about 10,000 years ago was in part associated with the formation of Askja caldera. Many postglacial eruptions also occurred along the ring-fracture. A major explosive eruption on the SE caldera margin in 1875 was one of Iceland's largest during historical time. It resulted in the formation of a smaller 4.5-km-wide caldera, now filled by Öskjuvatn lake, that truncates the rim of the larger central caldera. The 100-km-long Askja fissure swarm, which includes the Sveinagja graben, is also related to the Askja volcanic system, as are several small shield volcanoes such as Kollatadyngja. Twentieth-century eruptions at Askja have produced lava flows from vents located mostly near Öskjuvatn lake.

Leap has begun in Gr?msv?tn

Leap has begun in Gr?msv?tn. Can be expected to haupi? be similar to what happened last time the glaciers ran right for six years. Gunnar Sigurdsson, he is a hydrographic service, has earned the measurements in the western glacier and in pace this weekend.
He says the water level in Gr?msv?tn become the way that can be expected from the circuit. There seems to be begun.

Last time there was gel in Gr?msv?tn in 2004 it started the exact same time and now it's the end of October / November. Gunnar suppose further that the race now will be a similar format as last time. That race peaked at 5 to 6 days.

Gunnar says peak flow has gone over 3000 cubic meters per second. Would expect something similar now, but is not possible to know without more observations.

He says that as yet is no reason to close the road or evacuate the area by any means. Although that has grown considerably in the river is still little in it. Tourists who take the lead did not notice that this is anything more than usual.

More likely than not that that it erupt in Gr?msv?tn progresses towards the end of the gel. It happened in 2004 when vatnsfarginu relief of Grim waters in the second half of the gel.

Icelandic to English translation

Gel is taking up the West river, the water comes from Gr?msv?tn. Gunnar Sigurdsson, hydrographic man and an expert in service, says that may take 4-5 days for the race to reach the peak.

"I think it is possible to say that race has started in the West. It is rather cold weather and reduced flow in other rivers and increase the harp. The water levels have risen about 30 cm in the day and has increased productivity, "Gunnar said.

Skei?ar?rj?kull rivers are dry and not even certain that any water come down the stream, however, that jelly comes from Gr?msv?tn. The reason is that major changes have occurred to the point of ice. Glacier can group and it runs all the water that comes from the glacier west with him and the West. Gunnar did not know how the race would be to develop. Potential would all run harps. If that happened, it would be the first race of Gr?msv?tn that behave that way.

In measuring the flow of the day turned out to be West 130 cubic meters per second. Gunnar said that productivity in the river was about twice higher than in the normal glacial. It was not very high compared to gel, but he said he'd expect the conductivity should be expected to rise.

Hydrographic They will monitor the race tomorrow and the next day. Well is also monitored in jar?hr?ringu Gr?msv?tn. It is not impossible that there be up and erupt in relation to race.

Re: Iceland - Vatnaj?kull glacier: several small earthquakes recently

A j?kulhlaup from Gr?msv?tn

Fr? vatnsh??arm?li ? G?gjukv?sl 31. okt.-1. n?v. 2010

1.11.2010

On October 31, a glacier outburst flood (j?kulhlaup*) emerged from beneath the Skei?ar?rj?kull glacier, a southern outlet of the Vatnaj?kull ice cap. The floodwaters originate in the subglacial lake Gr?msv?tn, 50 km upstream from the glacier margin. The lake has been a source of such floods for centuries, but the size of the floods has varied greatly. The present flood is small and no threat to roads and bridges is imminent.
...

Observations on the bridge over the river G?gjukv?sl, which drains part of the glacier, confirmed a steady water level increase that indicated the onset of a j?kulhlaup (see top part of graph). Measurements between 2 and 3 PM on Oct. 31 indicated a discharge of 143 m<SUP>3</SUP>/s (cubic meters per second) and the water was confined to a narrow part of the channel. Between 9 and 10 AM on November 1, the discharge had increased to 455 m<SUP>3</SUP>/s, filling most of the river channel underneath the bridge.

The automated hydrometric station at G?gjukv?sl shows that the water level has increased by 1 metre during 20 hours (from 14 PM Oct. 31 to 10 AM Nov. 1). Since the floodwaters dig into the river bed, spread out and frequently change their course it must be kept in mind that the water level measured at a fixed location can only be viewed as an indicator of discharge. More extensive and repeated measurements at several places are therefore needed during j?kulhlaups to determine the actual size of the flood.

The electric conductivity of the river water has increased considerably (see the lowest of the 3 graphs). This indicates that geothermal fluids originating in the volcanic system beneath Gr?msv?tn have mixed with the subglacial lake waters and now form a component of the floodwater.
...

An earthquake of magnitude 3.0 on the Richter scale occurred underneath the Gr?msfjall mountain in Vatnaj?kull on the night before first indications of the j?kulhlaup were observed. Gr?msfjall is situated adjacent to the Gr?msv?tn subglacial lake (the source of the flood), and earthquakes and other tectonic movements associated with flooding are recorded by instruments on the mountain. Activity has subsided today.

Scientists will continue to monitor events in Gr?msv?tn and beneath Skei?ar?rj?kull very closely as the j?kulhlaup progresses in the coming days, see additional information compiled during a sequence of events in 2004.

Iceland on volcano alert with new threat of fresh eruption
by ClickGreen staff. Published Tue 08 Feb 2011 14:45, Last updated: 2011-02-08

Geologists on Iceland are warning of the increased risk of a fresh volcanic eruption after measuring an increased swarm of earthquakes around the island's second largest volcano.

P?ll Einarsson, a professor of geophysics at the University of Iceland, says the area around B?rdarbunga is showing signs of increased activity, which provides ?good reason to worry?...

Re: Iceland - Vatnaj?kull glacier: several small earthquakes recently

Icelandic Meteorological Office (IMO)

Specialist remark

Presently, there are no signs of an imminent volcanic eruption in Iceland. The Icelandic Meteorological Office (IMO) did not issue a warning last weekend in connection with increased seismicity beneath the Vatnaj?kull ice-cap. If signs of an eruption were apparent, IMO would issue a warning immediately.
