Danau volcanThe Danau volcano is a caldera at the western end of Java Island. It formed less than 10,000 years ago and is flaked by the remains of two older startovolcanoes (Pulosari and Karang). Inside the caldera, about 10 geothermal areas with hot springs are active, along a NE-SW trend.
Introduction:The Danau caldera, that is also called "Karang volcano" was formed in the Pleistocene by huge eruptions of pumice and debris. After the first eruption phases a 15 km wide caldera was formed, when parts of the magmachamber broke into. Later two stratovolcanoes (Pulosari and Karang) of andesitic and basaltic content were built up (probably about 10.000 - 25.000 years ago). Today`s activities are shown by some geothermal fields (at the craters Kawah Welirang and Kawah Hajiwith) hot springs on a NE-SW fault system. The forested area is a national nature resort.
