Karymsky volcano (Kamchatka), activity update: ash clouds and possible explosions

It was reported that seismic activity at Karymsky was above background levels during 29 August-5 September. Explosions may have generated ash plumes to an altitude of 3.8 km (12,500 ft) and the analysis of satellite imagery revealed ash plumes drifting SE on 29
August and a thermal anomaly in the crater during 29-31 August. The Level of Concern Color Code remained at Orange. Based on analysis of satellite imagery, the Tokyo VAAC reported that
on 7 September an ash plume rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted E.

Based on interpretations of seismic data, possible ash plumes rose to an altitude of 3.1 km (10,200 ft) a.s.l. on 8, 10, 11, and 14 August. Analysis of satellite imagery revealed a thermal anomaly in the crater on 11 August; clouds inhibited views on other days. The Level of Concern Color Code remained at Orange. ... lire toutes

Seismic activity at Karymsky was above background levels during 17-24 August, with 300-800 shallow earthquakes occurring daily. Based on seismic interpretation, ash plumes may have risen to an altitude of 5.7 km (18,700 ft) a.s.l. Observations of satellite imagery revealed that a thermal anomaly was present in the crater on 20 and 23 August. The Level of Concern Color Code remained at Orange. ... lire toutes

During the past week, activity at Karymsky volcano had been decreasing, although sprodic strombolian ash explosions are still occurring. After a temporary decrease from Orange to Yellow, KVERT raised the alert level back to Orange, following an explosion on 9 June. ... lire toutes

Karymski stratovolcano continues to be very active. Frequent explosions produce ash plumes of 2-3 km height, probably accompanied by pyroclastic flows. Explosion-type earthquakes range from 100-350 events per day. Direct visual observations are difficult or impossible due to bad weather. lire toutes

Background:

Karymsky, the most active volcano of  Kamchatka's eastern volcanic zone, is a symmetrical stratovolcano constructed within a 5-km-wide caldera that formed during the early Holocene.  The caldera cuts the south side of the Pleistocene Dvor volcano and is located outside the north margin of the large mid-Pleistocene Polovinka caldera, which contains the smaller Akademia Nauk and Odnoboky calderas. 
Most seismicity preceding Karymsky eruptions originated beneath Akademia Nauk caldera, which is located immediately south of Karymsky volcano.  The caldera enclosing Karymsky volcano formed about 7600-7700 radiocarbon years ago; construction of the Karymsky stratovolcano began about 2000 years later.  The latest eruptive period began about 500 years ago, following a 2300-year quiescence.  Much of the cone is mantled by lava flows less than 200 years old.  Historical eruptions have been vulcanian or vulcanian-strombolian with moderate explosive activity and occasional lava flows from the summit crater.
