The Dieng plateau in the highlands of central Java is renownedboth for the variety of its volcanic scenery and as a sacred areahousing Java's oldest Hindu temples, dating back to the 9th centuryAD. The Dieng volcanic complex consists of two or morestratovolcanoes and more than 20 small craters and cones ofPleistocene-to-Holocene age over a 6 x 14 km area. Prahustratovolcano was truncated by a large Pleistocene caldera, whichwas subsequently filled by a series of dissected to youthful cones,lava domes, and craters, many containing lakes. Lava flows covermuch of the plateau, but have not occurred in historical time, whenactivity has been restricted to minor phreatic eruptions. Toxic volcanic gas emission has caused fatalitiesand is a hazard at several craters. The abundant thermal features that dot the plateau and high heat flowmake Dieng a major geothermal prospect.
