PHILIPPINE VOLCANOES AND PLATE TECTONICS

This map shows the distribution of active, inactive, and potentially active volcanoes in the Philippines. The country is sitting on a tectonic setting that is ideal for the formation of volcanoes. 

Volcanoes in the Philippines are produced at the intersection of the Philippine Plate and the Eurasian Plate. The Philippine belong to the Pacific Ring of Fire, where the oceanic Philippine plate and other micro-plates are subducting along the Philippine Trench, Luzon Trench, Sulu Trench, and other small trenches. The subduction of these plates along the said trenches produces a discontinuous line of active volcanoes. There are 23 active volcanoes in the country. Included in the list of active volcanoes are Mayon, Taal, Pinatubo, Banahaw, Bulusan, Hibok-Hibok, and Kanlaon.
