KVERT reported that seismic activity at Shiveluch was above background levels during 31 October-7 November. Based on interpretations of seismic data, ash plumes rose to an altitude of 5.2 km (17,100 ft) a.s.l. A large number of daily hot avalanches were observed descending the lava dome and producing ash plumes on 2, 3, and 5 November that rose to an altitude of 3.5 km (11,500 ft) a.s.l. Fumarolic activity was visible on the web camera during 2-3 and 5-6 November. Analysis of satellite imagery revealed a thermal anomaly on the lava dome on 31 October and 1, 2, 3, and 6 November. The Level of Concern Color Code remained at Orange.
Based on information from KEMSD and analysis of satellite imagery, the Tokyo VAAC reported that during 8-10 November eruptions produced plumes to altitudes of 4.9-5.8 km (16,000-19,000 ft) a.s.l.
