Jenny Anne Barretto is a Filipino Marine Geophysicist.

She discovered the largest known caldera in the world, the Apolaki Caldera within the Benham Rise.

A caldera is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber/reservoir in a volcanic eruption.

The name “Apolaki” means “giant lord” in Filipino and is the mythical god of the sun and war.

The Apolaki Caldera is a volcanic caldera with a diameter of 150 kilometers (93 mi), making it the world’s largest caldera. It is more than twice the size of the Yellowstone in the USA.
