The Philippine Rise
(formerly known as Benham Rise) is an extended continental shelf
area of the Philippines, in a large igneous province covering an
area of 135,506 square kilometer of seabed, located east of Luzon.
The Philippine Rise, is an extinct volcanic
ridge located in the Philippine Sea approximately 250 kilometers
(160 mi) east of the northern coastline of Dinapigue, Isabela. The
rise has been known to the people of Catanduanes as Kalipung-awan as
early as the precolonial era of the Philippines, which literally
means "loneliness from an isolated place".
Under the Philippine Sea
lie a number of basins including the West Philippine Sea Basin,
inside of which is located the Central Basin Fault (CBF). The
Philippine Plateau is located in the CBF and its basement probably
is 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.
The Philippines claimed this feature as part of
its continental shelf in a claim filed with the United
Nations Commission on the Limits of the Continental Shelf on April
8, 2009, and which was approved under the United Nations Convention
on the Law of the Sea (UNCLOS) in 2012.
The rise is designated
as a "protected food supply exclusive zone" by the Philippine
government since May 2017. Mining and oil exploration are banned in
the Philippine Plateau as it is a protected area. On May 16, 2017,
President Rodrigo Duterte signed Executive Order No. 25, renaming
the feature to "Philippine Rise".
