Mount Batur

Mount Batur is an active volcano in Bali, Indonesia, characterized by two concentric calderas formed by collapses of the magma chamber approximately 29,300 and 20,150 years ago. The volcano features a 700-meter-tall stratovolcano and has a history of mild-to-moderate eruptions, with the first documented eruption occurring in 1804 and the most recent in 2000. The substantial lava field from the 1968 eruption is still visible today.

Mount Batur 

(Gunung Batur) is an active volcano located at the center of two


concentric calderas north west of Mount Agung on the island of Bali, Indonesia.[1] The south
east 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.[2] Another estimate of the inner caldera's formation date, formed during
emplacement of the Bali (or Ubud) ignimbrite, has been dated at about 23,670 and 28,500 years
ago.

The eruption that brought this volcano to be visible above the ocean is one of the most
forceful across the Earth.[citation needed] This volcano is marked by a collapsed top, called
a caldera.
The southeast 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.
Historical 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 over its history.
[3]
The caldera contains an active, 700-metre-tall stratovolcano rising above the surface of
Lake Batur. The first documented eruption of Batur was in 1804, and it has been
frequently active since then, most recently in 2000.[3][4] The substantial lava field from
the 1968 eruption is visible today when viewed from Kintamani, a town on the southwest
ridge of the caldera.
