GEOLOGIC HISTORY

Tangkubanparahu is a broad shield-like stratovolcano overlooking the city of Bandung that 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 rim of Sunda caldera forms a prominent ridge on the western side; elsewhere the caldera rim is largely buried by deposits of Tangkubanparahu volcano.

Historic Activity:

  • Eruptions have occurred in 1829, 1842, 1846, 1896, 1910, 1926, 1929, 1952, and 1967.
  • 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.

Recent Activity:

  • The most recent reported eruption was in 1969, when phreatic activity produced a thin ash layer on all sides of the volcano. Increased thermal activity in 1971 ejected small columns of mud. Since mid-1983 perioditic increases in seismicity, thermal activity, and inflation have occurred.
