Explosive activity at Shiveluch continued during 7-13 April. Ground-based observers and satellite imagery indicated that a viscous lava flow continued to effuse in the crater formed during a 2010 eruption.
Satellite imagery showed a weak thermal anomaly daily on the lava dome, and ash plumes that drifted 210 km SW and SE on 6, 8, and 11 April. Seismic data indicated that ash plumes potentially rose to an altitude of 7.7 km (25,000 ft) a.s.l. during 7-8 and 10-12 April, and to an altitude of 4.5 km (14,800 ft) a.s.l. on the other days. Observers confirmed that an ash plume rose to an altitude of 5 km (16,400 ft) a.s.l. on 8 April.
