Karymsky, Russia

KVERT reported that seismic activity at Karymsky was above background levels on 18, 19, and 23 July and at background levels during 20-22 and 24-25. Explosive activity that produced ashfall was seen by area volcanologists. Interpretation of the seismic data suggested that on 19, 21, and 23 July possible ash-and-gas plumes rose to altitudes of 3 km (10,000 ft) a.s.l. Observations of satellite imagery revealed a thermal anomaly in the crater during 19-21 July. The Level of Concern Color Code was raised to Orange.

Based on information from the Yelizovo Airport (UHPP), the Tokyo VAAC reported that on 25 July an ash plume rose to an altitude of 6.1 km (20,000 ft) a.s.l. and drifted NE.
