Strong explosive activity at Shiveluch continued during 4-11 May. Ground-based observers and satellite imagery indicated that a viscous lava flow continued to effuse in the active crater and was accompanied by fumarolic activity.
Seismic data and visual observations showed that ash plumes rose to altitudes of 10 and 5 km (32,800 and 16,400 ft) a.s.l. on 5 May and during 6-8 May, respectively. Satellite imagery showed a thermal anomaly on the lava dome during 4-5 and 8-10 May. Ash plumes drifted 800 km SE on 5 May, and an ash cloud 95 km SE of the volcano was observed on 7 May.
