A gas-and-steam plume rises above the summit crater of Cleveland on 23 June 1987. The upper flanks are darkened by ashfall from an eruption that began on 19 June. A lava flow began on 23 June and eventually descended 2.5 km down the ESE flank. Lava fountaining was observed on 22 July. A large explosive eruption took place on 28 August, the last day of the eruption. This view from the ENE show part of Herbert volcano behind the plume to the left.
