スンビン山

Gunung Sumbing is a stratovolcano that is the SE-most edifice of a chain of volcanoes in central Java that includes Sundoro and the Dieng Complex. Prominent cones are located on the N and SE flanks. An 800-m-wide summit crater is breached to the NE, but is partially filled by a lava dome that extended beyond the original crater rim. Emplacement of the dome followed the production of extensive pyroclastic flows down the NE flank. Activity reported in about 1730 CE may have produced the small phreatic craters found at the summit behind the dome.
