The Benham Rise, formally designated as Philippine Rise (Filipino: Talampas ng Pilipinas) by the Philippine government, is an extinct volcanic ridge located in the Philippine Sea approximately 250 kilometers (160 mi) east of the northern coastline of Dinapigue, Isabela. The feature has long been known to the people of Catanduanes as Kalipung-awan, which literally means “loneliness from an isolated place”, since the precolonial era.
Under the Philippine Sea lie a number of basins including the West Philippine Basin, inside of which is located the Central Basin Fault (CBF). Philippine Rise is located in the CBF and its geologic basement is probably a micro-continent. Several scientific surveys have been made on the feature to study its nature and its impact on tectonic subduction, including one about its effects on the 1990 Luzon earthquake.
