Re: Karymsky volcano on Kamchatka spews ash column to 4,5 km

Here are volcanic expressions of the last few weeks, sincere thanks to Cosmic Bob

Chaiten, Chile

Chait?n erupted on 2 May, following increased seismicity in the region the day before.

A pulsating white to gray ash plume rose to an estimated altitude greater than 21 km (68,900 ft) a.s.l. and drifted SSE.

The Alert Level was raised to Red.

Based on observations of satellite imagery and pilot reports, the Buenos Aires VAAC reported an ash plume at altitudes of 13.7-16.8 km (45,000-55,000 ft) a.s.l. drifted NE.

According to news articles, Chile?s government declared a state of emergency on 2 May and several hundred people were evacuated from the town of Chait?n (10 km SE).

The eruption was initially thought to have been from Minchinm?vida, about 17 km ENE, which last erupted in 1835.

According to news sources, ashfall was reported during 2-6 May both locally and up to hundreds of kilometers away, affecting water supplies and roads.

Based on observations of satellite imagery and pilot reports, the Buenos Aires VAAC reported that during 3-6 May ash plume rose to altitudes of 7-10.7 km (23,000-35,000 ft) a.s.l. and drifted SE, E, W, and NE. News sources indicated that about 4,000-5,000 people were evacuated from the town of Chait?n and surrounding areas as the eruption continued.

On 5 May, ONEMI (Oficina Nacional de Emergencia - Ministerio del Interior) reported that evacuations took place in Futaleuf?, about 65 km ESE, where about 30 cm of ash accumulated.

One elderly person died during the evacuation efforts. On 6 May, ONEMI and SERNAGEOMIN reported that the eruption became more forceful and generated a wider and darker gray ash plume to an estimated altitude of 30 km (98,400 ft) a.s.l.

All remaining people in Chait?n were ordered to evacuate, as well as anyone within 50 km of the volcano.

Veniaminof, Alaska Peninsula, USA

AVO reported on 3 May that the Volcanic Alert Level for Veniaminof was lowered to Normal and the Aviation Color Code was lowered to Green due to the absence of ash emissions and elevated surface temperatures. Seismicity was still above past background levels, but the rate and intensity had declined over the previous several weeks.

Tungurahua, Ecuador

The IG reported that although visual observations were occasionally limited due to cloud cover during 29 April-6 May, ash-and-steam plumes from Tungurahua were spotted and generally rose to altitudes of 5.5-7 km (18,000-23,000 ft) a.s.l.

Ashfall was reported in areas to the SW and W during 29 April-1 May and on 4 May.

On 30 April, explosions produced steam-and-ash plumes to altitudes of 9-10 km (29,500-32,800 ft) a.s.l. Incandescence at the summit was visible and incandescent blocks rolled down the flanks. Roaring noises were audible.

On 1 May, explosions were accompanied by ?cannon shots? and intense incandescence at the summit. Windows vibrated in areas 6 km NE. Incandescent blocks rolled 1 km down the flanks. On 3 May, a small lahar descended the W flank.

Soufri?re Hills, Montserrat, West Indies

MVO reported that during 25 April-2 May the level of volcano-tectonic earthquakes at Soufri?re Hills increased and was the highest since February 2006.

Degassing from a vent above Gages Wall was audible in the St. George?s Hill area to the NW. Steaming from the area above Tyre?s Ghaut to the NW was visible.

The Alert Level remained elevated at 4 (on a scale of 0-5).

Kilauea, Hawaii, USA

Based on visual observations from HVO and National Park Service (NPS) crews and web camera views, HVO reported that during 30 April-6 May lava flowed SE through a lava tube system underneath Kilauea?s Thanksgiving Eve Breakout (TEB) and rootless shield complex to the Waikupanaha ocean entry.

On 4 May, lava flows from breakouts on the pali reached the coastal plain. Kilauea summit earthquakes were located beneath the Halema?uma?u crater, along the S-flank faults, and along the SW and E rift zones.

The eruption from the vent in Halema?uma?u Crater continued to produce white plumes with minor ash content that drifted mainly SW. During most nights incandescence was seen at the base of the plume. Seismic tremor was elevated. The sulfur dioxide emission rate was high and fluctuated between 540 and 1,250 tonnes per day during 30 April-5 May. The background rate was 150-200 tonnes per day.

Karymsky, Russia

KVERT reported that seismic activity at Karymsky was at background levels during 25 April-2 May. Possible activity was characterized by gas-and-ash plumes that rose to altitudes of 2-2.5 km (6,600-8,200 ft) a.s.l.

Based on seismic interpretation, a gas-and-ash explosion may have occurred on 26 April. Observations of satellite imagery revealed that a thermal anomaly was present in the crater on 25, 27, and 28 April.

Based on airport data and information from KEMSD, the Tokyo VAAC reported that an eruption plume rose to altitudes of 3.7 km (10,000-17,000 ft) a.s.l. during 6-7 May.

Ash was not detected on satellite imagery. The Level of Concern Color Code remained at Orange.

Chaiten, Chile

The 1.200-meter high snowcapped Chaiten volcano in the Los Lagos Region, (lakes region) close to Puerto Montt and 1.200 kilometers south of Santiago started rumbling Thursday May 1st.

The Chaiten volcano spewed lava and blasted ash 12 miles (20 kilometers) into the sky, prompting officials to order a total evacuation of the nearby area driving more than 7,000 people from their homes.

Armed with a court order for people to leave an area within a 30-mile (50-kilometer) radius of the mountain, authorities forcibly removed about 130 holdouts, mostly small farmers. Many of their livestock were beginning to die from breathing air and drinking water clogged with volcanic ash. What is worse, it that the enormous slow-moving ash plume is expected to reach the Argentine capital, Buenos Aires (where about eight million people live), spreading airborne ash particles which, health officials said, could be highly dangerous to inhale.

Ubinas, Peru

Based on pilot reports, SIGMET reports, and observations of satellite imagery, the Buenos Aires VAAC reported that ash plumes from Ubinas rose to altitudes of 5.5-7.6 km (18,000-25,000 ft) a.s.l. and drifted ESE and NE during 19-22 April.

Tungurahua, Ecuador

The IG reported that although visual observations were mostly limited due to cloud cover during 16-22 April, ash-and-steam plumes from Tungurahua were spotted on 16, 20, and 21 April and rose to altitudes of 6-8 km (19,700-26,200 ft) a.s.l.

Strombolian activity at the crater was noted at night on 15 and 20 April.

During 16-19 April, explosions were registered by the seismic network. Ash plumes drifted W and SW; ashfall was reported in areas downwind during 19, 20, and 21 April. On 21 April a lahar disrupted the Ambato-Ba?os route for a few hours.

Soufri?re Hills, Montserrat, West Indies

MVO reported that during 4-18 April the lava dome at Soufri?re Hills changed very little, based on measurable parameters.

Overflights on 9 and 16 April revealed that the E side of the lava dome continued to erode and exposed more resistant solid material below.

A small pyroclastic flow traveled 500 m down the E flank on 10 April and generated a small ash plume that quickly dissipated to the W. Two more pyroclastic flows were observed on 16 April. The larger flow traveled 1 km down the E flank and was followed by relatively strong degassing. The Alert Level remained elevated at 4 (on a scale of 0-5).
