KVERT reported that seismic activity at Karymsky was slightly above background levels during 1-4 June and at background levels the other days during 30 May-6 June. Gas-and-ash explosions that produced plumes to an altitude of 2.3 km (7,500 ft) a.s.l. may have occurred during days of slightly elevated seismicity. Observations of satellite imagery revealed thermal anomalies in the crater during 1-4 June and a gas-and-steam plume that drifted 61 km SE on 2 June. The Level of Concern Color Code remained at Orange.
