Location

The Danau caldera at the western end of Java Island belongs to the Gunung Karang volcano. It was formed in Pleistocene (+- 2,5 mil. years ago). 10000 years ago two andesitic to basaltic volcanoes erupted and built up a stratovolcano until 1778m altitude (Karang volcano). Some active hydrothermal systems with hot springs are the today´s last sign of activity.

Background:

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.
