BATURLocation: 8.242° S, 115.375° E Elevation: 1.717 mThe historically active Batur volcano is located at the centerof two concentric calderas NW of Agung volcano. The outer10 x 13.5 km wide caldera was formed during eruption of theBali (or Ubud) Ignimbrite about 29,300 years ago and nowcontains a caldera lake on its SE side, opposite the satelliticcone of 2152-m-high Gunung Abang, the topographic high ofthe Batur complex. The inner 6.4 x 9.4 km wide caldera wasformed about 20,150 years ago during eruption of theGunungkawi Ignimbrite. The SE wall of the inner caldera liesbeneath Lake Batur; Batur cone has been constructed withinthe inner caldera to a height above the outer caldera rim.The 1717-m-high Batur stratovolcano has produced ventsover much of the inner caldera, but a NE-SW fissure system has localized the Batur I, II, and III craters along thesummit ridge. Historical eruptions have been characterized by mild-to-moderate explosive activity sometimesaccompanied by lava emission. Basaltic lava flows from both summit and flank vents have reached the calderafloor and the shores of Lake Batur in historical time.
