A phase of intense activity occurred last night starting at 19:10 UTC, and lasting for about 40 minutes. The activity was probably a major collapse of the dome and/or accompanied by explosions. It produced a large ash plume rising to about 10-12 km altitude (VAAC Tokyo) into the atmosphere. Due to cloud cover, no direct observations could be made.

Based on visual observations and analyses of satellite data, KVERT reported that during 14-21 June a viscous lava flow effused on the N flank of Shiveluch's lava dome, accompanied by hot avalanches, incandescence, and fumarolic activity. On 22 June an explosion was detected by the seismic network at 1246 and lasted about four minutes. A second explosion at 1310 produced an ash plume observed with the web camera that rose to an altitude of 6 km (19,700 ft) a.s.l. and drifted NW.

Based on visual observations and analyses of satellite data, KVERT reported that during 7-14 June a viscous lava flow effused on the N flank of Shiveluch's lava dome, accompanied by hot avalanches, incandescence, and fumarolic activity. Satellite imagery showed a daily thermal anomaly on the lava dome. Based on notices from Yelizovo Airport (UHPP), the Tokyo VAAC reported that on 14 and 16 June ash plumes rose to an altitude of 4.6 km (15,000 ft) a.s.l. and drifted E.

An explosion occurred last night at 21:02 UTC lasting for 6.5 minutes and sending an ash plume to an estimated altitude of about 30,000 ft (7-8 km), KVERT reports. The eruption was not observed directly, but inferred from seismic data.

A possible explosion or partial lava dome collapse produced a modest ash plume yesterday rising to 12,000 ft (3.7 km) altitude (VAAC Tokyo). KVERT reports no significant changes and continues to record moderate tremor levels, indicating that magma continues to rise and slowly build up the lava dome.
