If the researchers' findings were confirmed, Apolaki wouldofficially become the largest known caldera on Earth. 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. Early on I realized that metallurgical engineering is heavy on chemistry, which I did not like, Barretto shares cheekily. Sign up for our weekly update on developments, trends and technological advancement in the hydrographic industry. Eruption Styles Caldera-forming eruptions are usually Ultra-Plinean with Volcanic Explosivity Index (VEI) value of 7 (Mega-colossal) to 8 (Apocalpytic). When Barretto was around 12 years old, her family decided to leave the city life and go back to their provincial life in Kidapawan. Filipinos, this is a world record for our country! It is located within the Benham Rise (Philippine Rise) and was discovered in 2019 by Jenny Anne Barretto, a Filipina marine geophysicist and her team. Celebration Kick-Off Event Live from Tokyo .

With a rim diameter of 150 kilometers, Apolaki is now the worlds largest known caldera, surpassing Yellowstone, which spans only 60 kilometers across. 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. Subsequent eruptions formed domes, cinder cones, and explosion pits on the caldera floor. Dearest foreign readers, did you know that the worlds largest caldera is found in the Philippine Sea?

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 last eruption took place 640,000 years ago putting us in an area of uncertainty whether or not the supervolcano will follow its previous trends. Pinatubo in Zambales, and the Taal Caldera in Batangas. After developing their model of these eruption processes, taking advantage of the myriad data available from Kilauea, they also compared the model's predictions to observations from similar eruptions driven by caldera collapse at other volcanoes. The study of the crest of Benham Rise showed it had more in common with calderas than impact craters, the paper said. The most recent supervolcanic eruption on Earth occurred 27,000 years ago at Taupo located at the center of New Zealand's north island.
