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.A strong seismic swarm occurred near Musuan in 1976, and again around mid-2011.Musuan is one of the active volcanoes in the Philippines, which are all part of the Pacific ring of fire.FloraMount Musuan's northern slope is still covered by a primary rainforest.
