Overview
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.
Description
Vulcanologists describe Gunung Batur as a 'double caldera', with one crater inside another. The outer crater is an oval about 14km long, with its western rim about 1500m above sea level. The inner is a classic volcano-shaped peak that reaches 1717m. Geological activity occurs regularly, and activity over the last decade has spawned several smaller cones on its western flank. There were major eruptions in 1917, 1926, and 1963.
