Batur

칼데라 · Indonesia · 1711m

The Batur cone on the island of Bali was constructed as a result of eruptions along a NE-SW-trending line of vents. It is located within a 7.5-km-wide inner caldera with its SE margin below a lake that fills part of the SE floor of an outer 10 x 13 km caldera. Historical lava flows have formed much of the far lake shore in this view.

지질학적 요약

The historically active Batur is located at the center of two concentric calderas NW of Agung volcano. The outer 10 x 13.5 km caldera was formed during eruption of the Bali (or Ubud) Ignimbrite about 29,300 years ago and now contains a caldera lake on its SE side, opposite the Gunung Abang cone, the topographic high of the complex. The inner 6.4 x 9.4 km caldera was formed about 20,150 years ago during eruption of the Gunungkawi Ignimbrite. The SE wall of the inner caldera lies beneath Lake Batur; Batur cone has been constructed within the inner caldera to a height above the outer caldera rim. The Batur stratovolcano has produced vents over much of the inner caldera, but a NE-SW fissure system has localized the Batur I, II, and III craters along the summit ridge. Recorded eruptions have been characterized by mild-to-moderate explosive activity sometimes accompanied by lava emission. Basaltic lava flows from both summit and flank vents have reached the caldera floor and the shores of Lake Batur in historical time.

영어 요약

Mount Batur is an active volcano located at the center of two concentric calderas northwest of Mount Agung on the island of Bali, Indonesia. The southeast side of the larger 10×13 km caldera contains a caldera lake. Both the larger caldera, and a smaller 7.5 km caldera were formed by a collapse of the magma chamber, the first larger collapse taking place about 29,300 years ago, and the second inner caldera collapsing about 20,150 years ago. Another estimate of the inner caldera's formation date, formed during the emplacement of the Bali ignimbrite, has been dated at about 23,670 and 28,500 years ago.
