Mandalagan

Elevation is 1885 metres (6,184 feet), with a base diameter of 26 kilometres. Mandalagan is a deeply dissected complex volcano, with a highly altered volcanic dome. Volcanic activity is reported to include seven volcanic centres, at least five craters and/or calderas up to 2 km in diameter, and a vigorous solfataric area at the highly altered volcanic dome structure. One solfataric area emits a high-temperature (106 degrees C) plume to 30 m height with a roaring noise like a high-pressure geothermal borehole. ==Images==

The Smithsonian listing has a satellite photograph of the general area. ==Geological Features==

Mandalagan is part of the Negros Volcanic Belt. Rock type is principally andesitic with some dacitic A crater located near the center called "Tinagong Dagat", where hikers camp. ==Eruption==

The most recent eruption produced a thin basaltic lava flow, but it is not known when this is likely to have occurred. ==Listings==

Philippine Institute of Volcanology and Seismology (PHIVOLCS) lists Mandalagan as potentially active. The Smithsonian Global Volcanism Program lists Mandalagan as fumarolic. ==See also==
