Small plumes rise above rockfalls accompanying renewed lava-dome growth at Sheveluch volcano on 22 August 1993. Intermittent mild explosions with a maximum cloud height of 5 km began on 11 April 1992. A large explosive eruption on 22 April produced an 18-km-high ash plume and pyroclastic flows. Renewed dome growth began that month, and by 27 May the lava dome had doubled its pre-eruption height to 400 m. Dome growth along with intermittent mild explosive activity continued until at least July 1994.
