On the southern flank of the volcano, two crater lakes are located, Lakes Danao and Malagsom. Hot Springs are located on the southern shore of Lake Danao (not to be confused with the other Lake Danao which is located near Ormoc City and part of Lake Danao Natural Park). Lake Malagsom is a crater lake with green acidic water.
Rocks primarily found on the volcano are andesite.
An eruption was reported to have occurred in 1895 but no further details are available.
Philippine Institute of Volcanology and Seismology (PHIVOLCS) classifies Mahangao as inactive volcano even with the active thermal features of the mountain.
