Mount Batur (Gunung Batur) is an active volcano located at the center of two concentric calderas north west of Mount Agung, Bali, Indonesia

The south east side of the larger 10×13 km caldera contains a caldera lake

The inner 7.5 kilometer wide caldera, which was formed during emplacement of the Bali (or Ubud) ignimbrite, has been dated at about 23,670 and 28,500 years ago

The southeast wall of the inner caldera lies beneath Lake Batur

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 in historical time

The caldera contains an active, 700-metre-tall stratovolcano rising

above the surface of Lake Batur

The first historically documented eruption of Batur was in 1804, and it has been

frequently active since then

The substantial lava field from the 1968 eruption is visible today when viewed from Kintamani, a town that stradles the southwest ridge of the greater caldera

The caldera is populated and includes the four main villages of Kedisan, Songan,

Trunyan and Toya Bungkah

The locals largely rely on agriculture for income but tourism has become increasingly popular due to the relatively straightforward trek to the summit of the central crater

The lake Danau Batur is the largest crater lake on the island of Bali

and is a good source of fish

On September 20, 2012 UNESCO has made Mount Batur Caldera

a part of the Global Geopark Network
