The Apolaki Caldera is a volcanic caldera 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 Filipino marine geophysicist and her team.
The Apolaki Caldera is about 150 km in diameter, making it the largest known Caldera in the world, and 90 km larger than the Yellowstone Caldera. [2] Its monumental size suggests that the magnetic pulses associated with its formation have had a significant impact on the physics and chemistry in its region of the Pacific Ocean. [2] The Apolaki ...

Caldera structure is similar on all of these planetary bodies, though the size varies considerably. The average caldera diameter on Venus is 68 km (42 mi). The average caldera diameter on Io is close to 40 km (25 mi), and the mode is 6 km (3.7 mi); Tvashtar Paterae is likely the largest caldera with a diameter of 290 km (180 mi). The average ...
The upward movement of the Yellowstone caldera floor between 2004 and 2008—almost 75 millimetres (3.0 in) each year—was more than three times greater than ever observed since such measurements began in 1923. [102] From 2004 to 2008, the land surface within the caldera moved upward as much as 8 inches (20 cm) at the White Lake GPS station.

Geologic map of the lake floor Crater Lake from space. Mount Mazama, part of the Cascade Range volcanic arc, was built up mostly of andesite, dacite, and rhyodacite over a period of at least 400,000 years. The caldera was created in a massive volcanic eruption between 6,000 and
