All times are local (unless otherwise noted)


At Tangkubanparahu "white thin smoke" was emitted from Upas Baru crater and Ratu crater on 14 April, and from Upas Baru crater on 15 April. On 14 and 15 April shallow and deep volcanic earthquakes were recorded. During this time visitors were banned from the volcano. On 19 April the Alert Level was reduced from 3 to 2 (on a scale of 1-4) and the volcano was opened to the public, but access was restricted around Ratu crater and not permitted at the other craters.

Geologic Background. Gunung Tangkuban Parahu is a broad shield-like stratovolcano overlooking Indonesia's former capital city of Bandung. The volcano was constructed within the 6 x 8 km Pleistocene Sunda caldera, which formed about 190,000 years ago. The volcano's low profile is the subject of legends referring to the mountain of the "upturned boat." The Sunda caldera rim forms a prominent ridge on the western side; elsewhere the rim is largely buried by deposits of the current volcano. The dominantly small phreatic eruptions recorded since the 19th century have originated from several nested craters within an elliptical 1 x 1.5 km summit depression.
