Shiveluch, Russia

KVERT reported that seismic activity at Shiveluch was above background levels during 6-13 February. Based on interpretations of seismic data, ash plumes likely rose to altitudes of 5.5 km (18,000 ft) a.s.l. Lava flows continued to be active on the S and N flanks. Analysis of satellite imagery revealed a thermal anomaly on the lava dome during 6 and 8-10 February; clouds prevented observations on the other days during the reporting period. The Level of Concern Color Code remained at Orange.

Based on information from KEMSD, the Tokyo VAAC reported that an eruption on 12 February produced a plume that rose to an altitude of 4.6 km (15,000 ft) a.s.l.
