A viscous lava flow is extruded down the east flank of the Novy lava dome on 10 March 1987, within a trough that formed in the dome during the 1985 eruption. Extrusion of rigid blocks was first seen on 9 December 1986. On 16 December lava extrusion began, accompanied by explosions producing 5-6 km high ash plumes and pyroclastic flows that reached out to 4 km. Quiet lava extrusion continued until March 1988. In late July 1988 incandescence was seen at the top of the dome, accompanied by minor ash plumes. Photo by Alexander Belousov, 1987 (Institute of Volcanology, Kamchatka, Russia).
