Karymsky, Russia

KVERT reported that seismic activity at Karymsky was above background levels on 11 and 12 May and at background levels the other days during 9-16 May. Gas-and-ash explosions that produced plumes to an altitude of 3.1 km (10,200 ft) a.s.l. may have occurred on 11 and 12 May. Observations of satellite imagery revealed that on 13 May a thermal anomaly was present in the crater and a steam plume drifted 7 km ESE. An ash plume at an altitude of 2 km (6,600 ft) a.s.l. was spotted on 15 May and drifted E. The Level of Concern Color Code remained at Orange.

Based on observations of sateliite imagery, the Tokyo VAAC reported that on 20 May an eruption plume rose to an altitude of 3.4 km (11,000 ft) a.s.l.
