KVERT reported that seismic activity at Karymsky was above background levels during 4-11 April. Based on seismic interpretation, weak ash-and-gas explosions or hot avalanches may have occurred daily during the reporting period. Observations of satellite imagery revealed that a thermal anomaly was present in the crater during 4-6 April and an ash plume drifted 70-80 km ESE on 8 April. The Level of Concern Color Code remained at Orange.
