Perbakti volcano

Perbakti is an eroded stratovolcano at the west of Mount Salak in West Java, Indonesia. The summit is elongated in a northwest-southwest direction, in which Gunung Endut volcano rises above a saddle of Perbakti. Two 2 km wide of depressions on the northern and the southern side has formed two rivers, the Kaluwung Herang and Pamatutan rivers. Fumaroles, mud pots and hot springs are located on the south and the southeast flanks.
