The volcanic island of Biliran, located across the narrow Biliran Strait from the northern tip of Leyte Island, contains many prominent andesitic lava domes, the highest of which is 1301 m Surio. Several Pleistocene K-Ar dates have been obtained from volcanic centers on northern Biliran Island. Fumarole fields are scattered throughout the 20 x 35 km wide island. The only known historical activity at Biliran was a phreatic explosive eruption and possible debris avalanche at a thermal area in 1939. -

Mount Biliran is an active volcano in the Philippines. It is a complex (compound) volcano, meaning that it has more than one feature. These volcanoes form because of changes of their eruptive characteristics or the location of multiple vents in an area. -

Biliran is a compound volcano that makes a large mountainous island just north of the island of Leyte.  Biliran's single historic eruption was from a flank vent in 1939. There are five solfatara fields on the island. The solfatara on the west side of Mt. Guinon contained more than 400 tones of sulfur in 1880. -
