The Philippines had to show that Benham Rise is morphologically connected to the Luzon landmass, explains Barretto in an interview with The LaSallian. Features like a breached rim, intra-caldera benches, and a resurgent dome indicate a multi-phase volcanic history consisting of both quiet and explosive eruptions. "Due to its enormous ~150km diameter, it may be easier to suppose that it is an impact crater rather than a volcanic caldera. The caldera has a diameter of ~150 km (93 miles), twice the size of the famous Yellowstone caldera in Wyoming (U.S.). When a volcano erupts vast amounts of magma in a short period, it may fall downhill into the emptied or partially emptied molten rock, producing a deep recession at the surface ranging in size from one to dozens of kilometers in diameter. The feature is on the crest of Benham Rise, an oceanic plateau off the Philippines coast. The caldera, because of its magnitude, was named Apolaki or "giant lord" after the Filipino mythical god of the sun and war. The initial eruption, which occurred 200,000 years ago triggered a "volcanic winter" from the massive amount of ash ejected into the atmosphere. Map by GNS A caldera is a depression created when a volcano collapses after the emptying of its magma chamber in an eruption, or the withdrawal of the magma. The term caldera has come to be associated with large volcanoes capable of producing powerful eruptions because many of the worlds largest extinct volcanoes are calderas. In our paper, we suggested that the formation of the Apolaki Caldera (the collapse) may not have been simply caused by magma withdrawal from its magma chamber. About 150km in diameter,the caldera is comparable to the biggest impact craters on Earth and bigger than any other known calderas on this planet. The chamber is mostly solid, with only about 5-15% melt.
