KVERT reported that seismic activity at Karymsky was at background levels on 9 and 13 August and slightly above background levels on the other days during 8-15 August. Based on interpretations of seismic data, possible ash plumes rose to an altitude of 3.1 km (10,200 ft) a.s.l. on 8, 10, 11, and 14 August. Analysis of satellite imagery revealed a thermal anomaly in the crater on 11 August; clouds inhibited views on other days. The Level of Concern Color Code remained at Orange.
Based on analysis of satellite imagery and information from KEMSD, the Tokyo VAAC reported that on 14 August an eruption plume rose to an altitude of 2.7 km (9,000 ft) a.s.l.
