An explosive eruption at the summit crater of Semeru on 17 August 1985. This activity is typical of Semeru, which has been in near-continuous eruptive activity since 1818, producing frequent small-to-moderate explosions that eject ash and volcanic bombs. Some larger eruptions have produced pyroclastic flows and lahars that have reached the foot of the volcano. Photo by Tom Casadevall, 1985 (U.S. Geological Survey).
