6.77°S, 107.6°E; summit elev. 2084 m
All times are local (unless otherwise noted)
Temperatures in Kawah Baru, a small vent on the W side of the summit crater, active during the 1896 eruption, rose steadily from 90 to 140°C in the two weeks prior to 9 December. No changes have been detected in the volcano's continuing low-level background seismicity.
Geologic Background. Tangkubanparahu (also known as Tangkuban Perahu) 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 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.
