Bratan or Catur or Tjatur is a dormant caldera/stratovolcano located at the northern side of Bali island in Indonesia. The volcanic complex covers an area of 11 by 6 kilometres (6.8 mi × 3.7 mi). The caldera contains 3 separate lakes (Tamblingan, Buyan, and Bratan) and 5 post-caldera volcanoes (Lesung, Tapak, Sengayang, Pohen, and Adeng).[3]
Volcanism at Bratan is the result of subduction as the Indo-Australian plate subducts under the Eurasian plate. Although there have been no eruptions in historic times, geothermal activity in the form of numerous hot springs and fumaroles heated by a magma chamber at depth.[4]
