Sundoro Volcano — Indonesia

Gunung Sundoro, in central Java, is located between the Dieng complex to the NW and Sumbing volcano to the SE. The large Kembang cone is about 2.5 km from the summit on the SW flank. A small lava dome occupies the summit crater, and numerous phreatic explosion vents are present in the summit area. Lava flows extend in all directions from the summit crater. Deposits of a large debris avalanche are located below the NE flank. Pyroclastic-flow deposits dated at 1,720 years before present extend as far as 13 km from the summit. Recorded eruptions typically have consisted of mild-to-moderate phreatic explosions, mostly from the summit crater. Flank vents were also active in 1882 and 1903.
