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.

The 35-km-long volcanic island of Biliran, located across the narrow Biliran Strait from the northern tip of Leyte Island (left), contains many prominent andesitic lava domes. Five fumarole fields are scattered throughout the roughly 35-km-long island. The only known historical activity was a phreatic explosive eruption at a thermal area in 1939.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
