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. Authors include Jenny Barrettoand Ray Wood from GNS Science, who were key scientists in atechnical working group on Benham Rise for the United Nations Convention on the Law of the Sea. 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. Ive mentored many people on their blogging journey. 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 agency also included rock samples and their chemical composition characteristics as additional support. The Apolaki Caldera is the worlds largest volcanic crater, with a diameter of 150 kilometers (93 miles). Their study also revealed for the first time the structure of the Benham Risealso called Philippine Risewhich is described as an oceanic large igneous province at the western margin of the Philippine Sea. The eruption ejected so much pyroclastic ash and lava that it left a 350-meter deep depression in the Earth's crust, with an outer rim reaching heights of 300 meters. Scientists have recently found something literally and figuratively massive hiding in the Philippine Rise (a.k.a. Apolaki on the crest of Benham Rise, undersea in the Philippines, could be the largest caldera on Earth. "[The eruptions] must have been huge to produce such a big crater structure and that would have an effect on climate at the time; this would have been millions of years ago.

When volcanic activity built-up the massive, igneous rocks range in age from 47.9 to 26 million years, for the first time, sonar scans of the seafloor showed the morphology. 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. The largest known impact craters on Earth include Chicxulub - caused by the asteroid that wiped out the dinosaurs nearly 66 million years ago - which is about 200km wide. The caldera was formed by hotspot-related magmas interacting with a broadening ridgeupward magma movement at the ocean bottom where the oceanic crust was forming, resulting in the merging and eventual separation of Benham Rise from surrounding geological features. With the researchs objective to present the features of the Philippine Rise given the limited data, Barretto and her research team subsequently made use of NAMRIAs data to describe the Apolaki caldera. Now, dearest readers, no worries! Though the eruption was tiny in volume compared to the 1980 eruption of Mount St. Helens, it . The chamber is mostly solid, with only about 5-15% melt. "For the area to be rich in oil, the volcano must be above water or there should be forests around," Solidum said, adding that the location where the caldera was discovered did not have any of those features.

The Benham Rise is rising from the 5.200 meters (~17,000 ft) deep seafloor to ~2500 meters, roughly 8,200 ft, beneath the sea surface, with a depression in the central portion, which likely is a volcanic caldera. With the multibeam bathymetry, a large area such as the Philippine Rise can be surveyed faster and more accurately as it uses transducers that convert electrical signals to acoustic pulses, and vice versa. Apolaki is one of few calderas in the Philippines, a list that includes the Corregidor in Bataan, Mt. Jenny Anne Barretto, a Filipina marine geophysicist based in New Zealand, recently published a paper, along with Ray Wood and John Milsom, describing the morphology and formation of the Benham Rise.

"Apolaki" means "giant lord" and is based on the Filipino mythical god of the sun and war. A caldera is a depression created when a volcano collapses after the emptying of itsmagma chamber in an eruption, orthe withdrawal of the magma. "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," they wrote. 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. Currently, Barretto is now working for GNS Science in New Zealand and is also a member of American Association of Petroleum Geologists and the Geological Society of the Philippines.
