The Dieng plateau in the highlands of central Java is renowned  both for the variety of its volcanic scenery and as a sacred area  housing Java's oldest Hindu temples, dating back to the 9th century  AD. The Dieng volcanic complex consists of two or more  stratovolcanoes and more than 20 small craters and cones of  Pleistocene-to-Holocene age over a 6 x 14 km area. Prahu  stratovolcano was truncated by a large Pleistocene caldera, which  was subsequently filled by a series of dissected to youthful cones,  lava domes, and craters, many containing lakes. Lava flows cover  much of the plateau, but have not occurred in historical time, when  activity has been restricted to minor phreatic eruptions. Toxic volcanic gas emission has caused fatalities  and is a hazard at several craters. The abundant thermal features that dot the plateau and high heat flow  make Dieng a major geothermal prospect.
