The Mandalagan volcano is located at latitude 10.65° North (10°39'0"N), longitude 123.25° East (123°15'0"E), in the province of Negros Occidental, on the north of the island of Negros of the Philippines.

Mandalagan is a solfataric, fumarolic, potentially active stratovolcano.

Physical Features

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 klms 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.

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 hiking tourists stay
