The YTT represents the largest known Quaternary eruption, ejecting about 3,800 km 3 (dense rock equivalent) of ash that covered ~40 million km 2 to a depth greater than 5 mm, plus another 1,500 km 3 of pyroclastic density current (PDC) deposits (Costa et al., 2014). 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. Sonar surveys of the seafloor also revealed the morphology for the first time. Located in Indonesia, the volcano that formed the Toba Caldera last erupted about 74,000 years ago. Their study also reveals that the caldera was formed by hotspot-related magmatism interacting with a spreading ridgethe upward magma movement at the ocean floor where the new crust was forming, leading to the joining and eventual separating of Benham Rise with surrounding geologic structures. With regard to the possibility of volcanic activity, Solidum explains that due to water pressure, undersea volcanoes are less likely to erupt. The sides and top of the volcano fall inward as the tectonic support given by the magma chamber vanishes. It erupted in 1952 and created a small island. This is a BETA experience.
