Karymsky, Russia

KVERT reported that seismic activity at Karymsky was at background levels during 25 April-2 May. Possible activity was characterized by gas-and-ash plumes that rose to altitudes of 2-2.5 km (6,600-8,200 ft) a.s.l. Based on seismic interpretation, a gas-and-ash explosion may have occurred on 26 April. Observations of satellite imagery revealed that a thermal anomaly was present in the crater on 25, 27, and 28 April. Based on airport data and information from KEMSD, the Tokyo VAAC reported that an eruption plume rose to altitudes of 3.7 km (10,000-17,000 ft) a.s.l. during 6-7 May. Ash was not detected on satellite imagery. The Level of Concern Color Code remained at Orange.
