Eruption at Bezymianny 17 December 2009

Bezymianny volcano on the Kamchatka peninsula is reported by KVERT to have erupted at 21:45 UTC on 16 December:

According to seismic data, an explosive eruption of the volcano began at 21: 45 UTC on December 16. Ash explosions > 10.0 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 began to increase from December 08, but a size of thermal anomaly – from December 16. At 17:07 UTC on December 16, a size of the thermal anomaly was 6 pixels and the temperature was +19.4 with -23 of background. No visual and video data – the volcano obscured by clouds. But possibly ash fall began occur at Kozyrevsk village from 22:25 UTC on December 16

Tokyo VAAC issued an ash advisory at 22:51 UTC reporting ash at FL320 (32,000 feet or 9750 metres). No further information as yet, and as the KVERT bulletin indicates the Bezymianny webcam is currently showing only a blank cloudy sky.

UPDATE. A further ash advisory from Tokyo, issued 23:41 UTC, reports ash up to FL350 (35,000 feet or 10,600 metres).

The Kamchatka Six: Russia’s volcanoes rock and rumble 24 August 2009

‘Six Kamchatka volcanoes exhibit activity simultaneously for the first time in sixty years’, announces a story in Vostok Media today: ‘”This is a rarity. For the first time in sixty years the six volcanoes show activity”, Kamchatka scientists from the Institute of Volcanology and Seismology stated. At present they are trying to figure out the reasons behind the increase of activity of the Kamchatka volcanoes’.

Kamchatka volcanic activity 24 August 2009

But which six volcanoes? The map above (adapted from the AVO activity map) shows the alert levels for the Kamchatka volcanoes, as reported by the Kamchatka Volcanoes Emergency Response Team (KVERT). The Vostok Media story lists Shiveluch, Kliuchevskoi, Bezymianny, Karymsky, Koryaksky and Gorely as the six active volcanoes in question. The last-named, they explain, may erupt soon: ‘Scientists agree that Gorely volcano might soon erupt for the first time in twenty two years. Water temperature of the lake located on top of the volcanic mountain is rising, which may well indicate oncoming eruption’.

However, Gorely isn’t active at the moment, and KVERT rate it Green. Shiveluch and Koryaksky are at Orange, and Kliuchevskoi, Karymsky and Bezymianny are at Yellow. Also at Yellow alert (since the end of July) is Kizimen: KVERT reports today that ‘Activity of the volcano continues. Strong explosive eruption possible in case of further seismicity increasing. Seismicity was above background levels on August 15 and 17-20; and at background levels in the other days of this week’ … so perhaps Kizimen rather than Gorely should have been in the Kamchatka Six.

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.

Russian and US scientists join forces to study Bezymianny 26 June 2008

From Russia comes news that Russian and US volcanologists are to join forces to study Bezymianny, one of the many active volcanoes of the Kamchatka Peninsula. The principal hazard posed by eruptive activity at Bezymianny is to aviation. KVERT, the organization that monitors the Kamchatka volcanoes, summarizes its hazards thus:

Moderate potential hazards are caused by ash plumes, ash falls, pyroclastic flows, hot avalanches and lahars. The volcano constitutes a potential hazard to international and local airlines at Kamchatka because its eruptive clouds can rise to a height of 8-15 km ASL and extend for hundreds of kilometers from the volcano to different directions.

In a project lasting several years, the Russian/US team will be installing modern seismic and other monitoring networks and probing the volcano’s eruptive processes. The project involves scientists from the Russian Institute of Volcanology and Seismology and the University of Alaska-Fairbanks.

Bezymianny was thought to be extinct until a violent eruption in 1955-6 proved otherwise. On 30 March 1956 an explosive eruption notably similar to that of Mount St Helens in 1980 took place: the upper 180m of the volcano was blown apart, leaving a crater 1.5km in width and projecting an eruption cloud to the east to a height of 40km, at an angle of between 30 and 40 degrees to the horizon. Trees were felled by the directed blast for 24km, and mudflows choked the Kamchatka River. Since then there has been lava-dome growth at Bezymianny, with intermittent explosive eruptions once or twice each year. The RIA-Novosti news agency observes that the 1955-6 eruption of Bezymianny had a profound impact on volcano awareness in the USSR (as it then was), and resulted in the establishment of permanent volcano monitoring stations and the institution of a Soviet Day of Volcanology on 30 March each year.*
