Galunggung is a stratovolcano on the west side of the island of Java. The caldera of Galunggung is open to the southside.
The "Ten Thousand Hills of Tasikmalaya" dotting the plain below the volcano are hill-size deposits (hummocks) left by a large debris-avalanche associated with the collapse forming the caldera ca. 4200 years ago.
Historical eruptions have been restricted to the central vent near the caldera headwall. The eruptions from Galunggung have often caused much damage: The first historical eruption in 1822 produced pyroclastic flows and lahars that killed over 4000 persons. Its last major eruption in 1982-1983 produced devastating pyroclastic flows causing large-scale damage in the populated areas around the volcano.
