Overview

Gunung Tangkuban Parahu is a broad 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.

Regional Volcanic Activity
The Sunda-Banda Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

The broad Tangkuban Parahu, known locally as the mountain of the "upturned boat," dominates the skyline immediately N of Indonesia's former capital city of Bandung. The volcano is truncated by the 6 x 8 km Pleistocene Sunda caldera. A series of nine overlapping craters form a 1 x 1.5 km wide elliptical depression at the summit of the post-caldera cone. Minor phreatic eruptions have occurred in historical time.
