CVGHM reported that seismicity at Tangkubanparahu increased significantly on 13 August; earthquakes continued to be recorded through 23 August. The Alert Level was raised to 2 (on a scale of 1-4). Visitors and residents were prohibited from going within a 1.5-km radius of the active crater.

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.
