Apolaki Caldera

The Apolaki Caldera is a volcanic crater with a diameter of 150 kilometers (93 mi), making it the world's largest caldera. 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. The name "Apolaki" means "giant lord" in Filipino. [1][2] The Rise has been known to the people of Catanduanes as Kalipung-awan since pre-colonial times, which literally means 'loneliness from an isolated place'.[3][4]

Geological history

Gravimetric analysis shows that the Benham Rise, as the submarine mountain massif is named, is made up of a nine miles thick layer of magmatic and volcanic rocks. Rock samples ages ranges from 47.9 to 26 million years, when volcanic activity made up the massif.[5]
