Musuan volcano, also known as Calayo, is an isolated, low grass-covered andesitic-to-dacitic lava dome and tuff cone that rises to 646 m above flat farmland in the province of Bukidnon in central Mindanao. An eruption, consisting of a possible phreatic explosion that "burned everything around it," was reported by a Jesuit priest to have occurred four years prior to his 1891 visit, at which time strong solfataric activity prevented closer examination. PHIVOLCS reported eruptions in 1866 and 1867. A strong earthquake swarm occurred near Musuan volcano in 1976.
