Bezymianny volcano (Kamchatka): new explosive eruption sends ash to 27,000 ft altitude
Friday Mar 09, 2012 08:00 AM | BY: TOMPFEIFFER
Following the steep increase of seismic activity a and eruption warning since 2 March, a new explosive eruption of Bezymianny volcano (the "volcano without name") in Kamchatka has started yesterday evening and is continuing.
According to Tokyo Ash Advisory Center, a plume is visible on Landsat imagery reaching flight level 270 (27,000 ft / around 9 km altitude) and extends 136 mi (220 km) to the north-east from the volcano.
KVERT reports that the "strong explosive eruption began about 21:27 UTC on March 08 and continues." Ash fall started to occur at Ust'-Kamchatsk Village from 01:30 UTC om March 09, and continues at present.

KVERT reported high levels of seismic activity at Bezymianny during 17-24 February and a thermal anomaly that was detected daily in satellite images. Two short volcanic tremor episodes were reported on 15 and 22 February. Gas-and-steam plumes, observed in satellite images, drifted NE on 20 and 22 February. ... [more]

KVERT reported that seismic activity increased at Bezymianny on 12 February and remained elevated through 19 February. The size and brightness of a thermal anomaly observed in satellite images both increased during this interval. Blocks possibly extruded from the top of the lava dome. KVERT raised the Aviation Color Code to Orange on 19 February. ... [more]

Earthquakes were detected in the vicinity of Bezymianny's lava dome during 23-24 May. Fumarolic activity was seen on 21 May and the temperature of the thermal anomaly detected in satellite imagery increased from 18 degrees Celsius on 19 May to 48.8 degrees Celsius on 23 May. So a increase of activity is possible. During 21-28satellite data showed a thermal anomaly over the lava dome and fumarolic activity was detected.Seismic data indicated that an explosive eruption began on 1 June, producing a large ash cloud about 127 by 93 km in dimension. Ash plumes from two explosions rose to altitudes of 8-10 km (26,200-32,800 ft) a.s.l. Ashfall was reported in Kozyrevsk village. Two bright thermal anomalies were seen in satellite imagery, possibly from pyroclastic flow deposits. [more]
