Benham Rise, the underwater landmass northeast of Luzon that the United Nations declared part of the Philippines’ continental shelf, has been grabbing headlines because of the presence of Chinese ships that may or may not have been given permission to do research in the area, according to conflicting claims by President Duterte, Defense chief Delfin Lorenzana, as well as Foreign Affairs officials. What remains undisputed, however, are the possible trove of mineral and gas deposits about 3,000 meters below the water’s surface that have yet to be discovered. Sometimes referred to as the Benham Plateau, the landmass, described to have a craggy or rough surface, is bigger than Luzon or almost half the size of the Philippine’s total land area. It extends eastward off the provinces of Aurora and Isabel, and the Bicol region, but has always been connected to Luzon’s landmass through the Bicol and Palanan saddles.
