Introduction:The Bratan caldera (also known as Catur or Tjatur caldera or the Buyan-Bratan volcanic complex) is surrounded by several younger stratovolcanoes on its southern rim, all densely vegetated and believed not to have erupted for hundreds or even thousands of years. The most prominent of these are:The largest post-caldera cone is Gunung Batukau (2276 m, 8.334 S / 115.090 E) 10 km to the SW. Gunung Pohan (2001 m, 8.283 S / 115.140 E) near the town of Bedugul. Gunung Lesong (1862 m, 8.296 S / 115.110 E) is a forested cone with a circular crater of 170 m depth having an unvegetated floor. Gunung Tapak and Gunung Lesong cones are older than the last large eruption of Batur, because they not covered by deposits of the youngest dacitic pumice eruptions of nearby Batur volcano, and must therefore be less than 23,000 years old. Inside the caldera, geothermal activity is exploited at the Buyan-Bratan geothermal power plant. There are numerous hot springs in the area. |
