Benham Plateau

Benham Plateau is an extinct underwater volcano located beneath the Philippine Sea east of Luzon Island. This submerged landform covers a vast area of seafloor in one of the country's most remote marine zones.

The Philippines gained international recognition of its control over the plateau in 2012 through a United Nations decision. This ruling significantly expanded the country's maritime boundaries.

Local communities of Catanduanes refer to this marine region as Kalipung-awan, reflecting the isolation experienced by fishermen in these distant waters.

Studying the plateau requires specialized research vessels and permits from Philippine authorities. Its protected status and isolated location mean that visits are scientific endeavors requiring careful planning.

Within the plateau lies the Apolaki Caldera, a massive volcanic crater of extraordinary size. This discovery made it the largest known caldera formation beneath the ocean's surface.
