Reports from Russia say that the Kamchatkan volcano Shiveluch has produced an ash emission to an estimated altitude (based on seismic data) of 7 km. KVERT reports that the ash plume was associated with a ‘shallow seismic event’ lasting four minutes. No ashfall on nearby settlements has been reported, and KVERT says that this event poses no danger to local communities.

No volcanic ash advisory has been issued by Tokyo VAAC for this event.

Activity at Shiveluch volcano, 3 October 2009 (NASA MODIS image)

The NASA Earth Observatory have published a new image of Shiveluch volcano on the Kamchatka Peninsula, captured on 3 October 2009 by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. The image shows a diffuse plume dispersing to the south-east. To the south-west of Shiveluch lies Kliuchevskoi volcano, which has also been active lately, although at the time this picture was taken it seems to have been going through a quiet interlude.

Shiveluch quieter, but activity continues 12 September 2009

Kamchatkan volcano Shiveluch has calmed down again after its latest burst of activity on 10-11 September. The Kamchatka Volcanoes Emergency Response Team (KVERT) have lowered the alert status from red to orange, and the latest volcanic ash advisory from Tokyo reports no emissions. However, the most recent KVERT bulletin, issued at 21:50 UTC on 11 September (archived here), makes it clear that activity at the volcano continues:

Activity of the volcano continues: a new viscous lava flow effuses at the lava dome. Ash explosions > 10 km (> 32,800 ft) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.

Seismic activity of the volcano decreased: only three explosive events occurred from 02:15 till 15:46 UTC on September 11. According to an interpretation of seismic signals, ash plumes rose up to 4.5-6.5 km (14,800-21,300 ft) ASL. No visual data about this events – the volcano obscures by clouds. According to satellite data, a thermal anomaly over the lava dome was registering on September 10-11.

The precise nature of this recent activity is unclear, but the reference to a ‘new viscous lava flow’ and the large explosions and ash plumes and reports of pyroclastic flows and ‘hot avalanches’ suggest a (partial?) dome collapse event. Until the weather clears and some visual data comes in (the Shiveluch webcam currently shows nothing but cloud) it’s impossible to be sure – and in any case, this phase of activity may not yet be over. Shiveluch is unusually active even for Kamchatka.

Reports from Russia indicate that a large eruption of Shiveluch began yesterday. A bulletin from the Kamchatka Volcanoes Emergency Response Team (KVERT), issued at 22:35 UTC on 10 September warns that ‘Ash explosions > 10 km (>32,800 ft) ASL from the volcano could affect international and low-flying aircraft’. According to the bulletin, ‘strong explosions’ occurred between around 14:19 and 14:55 UTC on 10 September, with seismic data indicating ash plumes reaching 15000 metres above sea level; if ash plumes are indeed reaching 10-15 km altitude, then this is a sizeable event. The bulletin reports that according to seismic data ’10 volcanic events (ash explosions and hot avalanches or pyroclastic flows) occurred at the lava dome from 16:33 till 20:25 UTC on September 10′. Whether the activity is still continuing is not clear, and there are no visual or satellite images of this event because of cloud cover.

Tokyo VAAC issued a volcanic ash advisory at 04:40 UTC today reporting emissions at FL210 (21000 feet / 6400 metres) at 02:16 UTC, but giving no subsequent eruption cloud observations. No further advisories have been issued, so perhaps things have calmed down again at Shiveluch.

The Russian press gives no additional information on this eruption, but reports that KVERT volcanologists have said that there is no danger to local inhabitants from this burst of activity.

New webcams for Russian volcanoes 24 June 2009

The Russian news agency RIA-Novosti reports that new cameras are to be installed to monitor Kliuchevskoi, Bezymianny and Shiveluch volcanoes in the north of the Kamchatka peninsula. Their images will be made available online. Apparently two new high-resolution cameras are to be installed that will update their images every minute (presumably one of the cameras will monitor both Kliuchevskoi and Bezymianny, which are near neighbours).

In a further illustration of the mass media’s firm belief that to illustrate a story about a volcano, a picture of any random volcano will do, the RIA-Novosti story features a photograph of Chaitén volcano in southern Chile.

Shiveluch volcano, 10 May 2009 (NASA Terra image)

The NASA Earth Observatory has published a lovely image today of the Kamchatkan volcano Shiveluch erupting, captured on 10 May 2009 the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite. The white colour of the northward-directed plume shows that it is predominantly steam, while brown ash deposits from previous eruptions blanket the snow around the volcano’s summit. Shiveluch is one of the most frequently active Kamchatka volcanoes.

Plume from Shiveluch volcano, 26 April 2009 (NASA MODIS/Terra image)

Shiveluch volcano in Kamchatka is continuing to erupt, producing a 7-kilometre ash plume according to this interestingly-phrased report from Russia Info-Centre. The latest bulletin from KVERT (issued 04:25 UTC today) reports ash plumes extending 250 kilometres NE of the volcano and reaching 5 kilometres altitude, and seismicity consisting of weak volcanic tremor and occasional shallow earthquakes. Ash explosions to above 10 kilometres, warns KVERT, could occur at any time.

The image above is from the NASA Earth Observatory, and shows the plume from Shiveluch on 26 April 2009, blowing SE towards the Bering Sea. This is a MODIS image from NASA’s Terra satellite.

A Russian-language report today from RIA-Novosti, which does not appear to be available in English, says that a new 30-metre-deep fissure has formed on the Molody Shiveluch (‘Young Shiveluch’) lava dome which is the focus of the current activity. The report quotes Alexei Ozerov of the Institute of Volcanology: ‘This fissure was formed over the last two days, and crosses the body of the volcanic dome in a south-easterly direction. It is continuously producing hot debris avalanches’. One pyroclastic flow may have destroyed a road and bridge on the Bekesh river, although the precise location is unclear. The report also notes that Koryaksky and Kliuchevskoi volcanoes in Kamchatka are also currently active, and that there is increased seismic activity at Gorely, which last erupted in 1986. This level of activity, however, is nothing unusual for Kamchatka.

This Shiveluch webcam enables you to peer through the trees at the volcano.

The Kamchatkan Volcanic Eruption Response Team (KVERT) have issued an information release (27 April, 01:05 UTC) for Shiveluch volcano in northern Kamchatka, reporting that seismic activity at the volcano has slightly decreased, with continuous tremor becoming intermittent and the number of weak shallow earthquakes declining, but the ‘danger of a strong explosive eruption’ remains, with explosive eruption of ash to 10 kilometers a.s.l. possible at any time. The current level of concern colour code for Shiveluch is given as Red.

Tokyo VAAC has a volcanic ash advisory notice for Shiveluch issued at 06:08 UTC reporting a possible eruption observed at 01:59 UTC, with ash at FL140 (14000 feet, 4300 metres).

A report from RIA-Novosti in Russia says that 170 tremors have been recorded over the last 24 hours at the Kamchatkan volcano Shiveluch, and that the volcano is erupting ash to an altitude of 4000m. According to this report the ash emission is ‘causing problems for air traffic’. The latest reports from Tokyo VAAC, however, indicate that although the eruption has been observed no significant ash cloud has been reported or is expected, and no warnings have been issued.

Shiveluch is a highly active volcano, ‘the most vigorous andesitic volcano of the Kuril-Kamchatka arc’, says the summary page at the Global Volcanism Program.

The Russian ITAR-TASS news agency reports today that Karymsky volcano on Kamchatka ‘has spewed an ash column to a height of 4.5 kilometres above sea level’ and that a ‘surge of seismic activity has been registered’. An information release from KVERT on 9 May 2008 warns that ‘Activity of the volcano continues and ash explosions up to 6 km (or 19,700 ft.) ASL could occur at any time’. The current alert level for Karymsky is orange.

KVERT also reports that activity at Shiveluch has decreased but ash explosions up to 10 km could occur at any time. As is almost always the case, avalanches and fumarolic activity are occurring at the lava dome, and thermal anomalies have been registered. The current alert level for Shiveluch is orange.
