KVERT reported that during 1-8 June explosive activity at Shiveluch continued.
Ground-based observers and satellite imagery indicated that a viscous lava flow continued to effuse in the active crater, accompanied by fumarolic activity. Observers noted that ash plumes rose to an altitude of 8.5 km (28,000 ft) a.s.l. on 2 June. Satellite imagery showed a thermal anomaly over the lava dome during 31 May and 1-4 June, and ash plumes drifting 152 km S and 250 km S and ENE during 2-3 June. Seismic data indicated that possible ash plumes rose to an altitude of 8 km (26,200 ft) a.s.l. on 5 June. The Aviation Color Code remained at Orange.
Based on analyses of seismic data, the Tokyo VAAC reported that a possible eruption on 6 June produced an ash plume that rose to an altitude of 8.2 km (27,000 ft) a.s.l. Ash was not detected in satellite images.
