KVERT reported that explosive activity at Shiveluch continued during 20-27 April. Ground-based observers and satellite imagery indicated that a viscous lava flow continued to effuse in the crater formed during a 2010 eruption and was accompanied by fumarolic activity. Seismic data and visual observations showed that ash plumes rose to an altitude greater than 10 km (32,800 ft) a.s.l. on 24 April and were slight on the other days.
Satellite imagery showed a weak thermal anomaly on the lava dome during 20-22 April, and ash plumes that drifted 396 km NE on 24 April. The Aviation Color Code remained at Orange.
