The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
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.
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.
