Eruptive activity has started in the form of intermittent ash explosions from the crater since 4 March. So far, the explosions were small and phreatic in origin (no fresh magma involved, caused by overheated groundwater), according to Surono, head of the Center for Volcanology and Geological Hazard Mitigation (PVMBG) in Bandung. ...

Typical eruption style: Explosive. Frequent phreatic explosions during the past centuries. Tangkubanparahu volcano eruptions: 1826, 1829, 1842, 1846, 1896, 1910, 1926, 1929, 1952, 1957, 1961, 1965, 1967, 1969, 1983, 1985(?) Last earthquakes nearby:
Background:Tangkuban Parahu was constructed within the 6 x 8 km Pleistocene Sunda caldera. The volcano's low profile is the subject of legends referring to the mountain of the "upturned boat."The age the caldera-forming eruption exceeds the >40,000 year range of radiocarbon dating (Newhall and Dzurisin, 1988). The rim of Sunda caldera forms a prominent ridge on the western side; elsewhere the caldera rim is largely buried by deposits of Tangkubanparahu volcano. The dominantly small phreatic historical eruptions recorded since the 19th century have originated from several nested craters within an elliptical 1 x 1.5 km summit depression. --- Sources: - GVP, Smithsonian Institution - Newhall C G, Dzurisin D, 1988.
