One of their recommendations is to back up the existence of Apolaki and its related structures through a seismic reflection survey, a method similar to bathymetry that utilizes a seismograph to detect and record seismic activity through a receiver. a caldera as a large basin-shaped volcanic depression. Eruptions of ash and pumice: The cataclysmic eruption started from a vent on the northeast side of the volcano as a towering column of ash, with pyroclastic flows spreading to the northeast.Caldera collapse: As more magma was erupted, cracks opened up around the summit, which began to collapse. It erupted in 1952 and created a small island.

Whether active or ancient, volcanic landforms found in national parks result from their eruption dynamics, with the volcanoes themselves and the lava flows and other deposits they leave behind serving as tangible evidence of the volcanic processes that formed them. [1][2], Gravimetric analysis shows that the Benham Rise, as the submarine mountain massif is named, is made up of a nine mile thick layer of magmatic and volcanic rocks. 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. Solidum also assures the public that the Apolaki is no longer active; its last eruption supposedly occurred millions of years ago, so there is little reason to worry about it erupting again.

In 2009, the Philippines filed a proposal to the United Nations Commission on the Limits of the Continental Shelf (UN-CLCS), arguing that Benham Rise is an extension of the countrys continental shelf, the submerged edge of a landmass. The National Mapping and Resource Information Authority (NAMRIA), a Philippine government agency mandated to be the countrys map-making and distributing center, conducted a multibeam bathymetry surveya process of measuring the depth of a body of water such as oceans, seas, and lakes by transmitting and receiving sound pulses from the seafloorin 2007, two years before it would be used to back the countrys claim on the territory.
