Merdada and Pangonan cones (Dieng Plateau, Central-Java)

The Dieng Plateau, or the 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. There are
numerous surface manifestations of hydrothermal activity, including lakes, fumaroles/solfatara and hotsprings. The last magmatic (as of 2019) eruption, thought to have occurred in the Dieng Volcanic Complex was at the Pakuwaja cone, during a eruption in 18th Century.The area is also known for the development of geothermal resources and lethal outbursts of gas. Scattered temples are the witnesses of the ancient Hindu culture that once reigned.
