Bezymianny volcano eruption news and activity updates:
Bezymianny volcano (Kamchatka) activity summary Aug - 4 Sep 2012 (explosive eruption 2 Sep)
Thursday Sep 06, 2012 06:01 AM | DOOR: T
KVERT reported that seismic activity at Bezymianny had increased in the middle of August. During 24-31 August levels were moderate; 17 events were recorded on 28 August and 71 events were recorded on 31 August. Observers noted weak-to-moderate fumarolic activity during 25-26 and 29 August; cloud cover prevented observations on the other days. A thermal anomaly was detected in satellite imagery on 25 August.
Based on seismic data analyses, an explosive eruption occurred from 0716 to 0745 on 2 September. Ash plumes rose to altitudes of 10-12 km (32,800-39,400 ft) a.s.l. and drifted more than 1,500 km ENE. A thermal anomaly observed in satellite imagery was very bright before the explosion. The Aviation Color Code was raised to Orange, then Red. Ash plumes rose to an altitude of 4 km (13,100 ft) a.s.l. and drifted NE later that day, then ash emissions ceased. Ash plumes continued to be detected in satellite imagery and drifted 450-600 km ENE and SE. The Aviation Color Code was lowered to Yellow. On 3 September seismic activity was low. A viscous lava flow effused on the lava-dome flank, and was accompanied by fumarolic activity and hot avalanches.

After the explosive eruption on 1 September, seismic activity of the volcano is now low, but a viscous lava flow continues to effuse on the lava dome flank and there are strong to moderate fumarolic activity and hot avalanches. The ash plume from the explosion was last seen yesterday drifting east of Kamchatka in the northern Pacific. [meer...]

A larger explosive eruption occurred at Bezyianni volcano in Kamchatka yesterday evening (1 Sep) around 19h15 GMT. The explosion produced an ash cloud rising to about 10 km altitude (flight level 340) and was first detected by Tokyo VAAC who sent out an ash-cloud aviation warning (major intercontinental routes pass this area). ...
