MOUNT MUSUAN
Mount Musuan is an ACTIVE lava dome and tuff cone which last erupted in 1891.
Musuan volcano is located on Mindanao Island. The volcano comprises a lava dome and tuff cone. The summit is at an elevation of 646m.
The Philippine Institute of Volcanology and Seismology reports that Musuan erupted in 1866 and 1867, but the Smithsonian Institution's Global Volcanism Program records another eruption, possibly phreatic, that "burned everything around it." The explosion supposedly occurred four years before the 1891 visit of a Jesuit priest, who reported that he could not examine the volcano more closely because of strong solfataric activity.
