KVERT reported that seismic activity at Shiveluch was above background levels during 3-10 October. Based on interpretations of seismic data, a large number of hot avalanches descended the lava dome and produced ash plumes that rose to an altitude of 4 km (13,100 ft) a.s.l. Fumarolic activity and gas-and-steam plumes that rose to an approximate altitude of 4.5 km (14,800 ft) a.s.l. were visible on the web camera during 2-5 and 7-9 October. Analysis of satellite imagery revealed a daily thermal anomaly on the lava dome and steam-and-ash plumes that drifted 30 km N and E on 6 and 7 October.
