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.
