Unlike if the volcano is on land, the atmospheric pressure is much less than the power of the volcano to explode, he adds. The pressurization is akin to squeezing the water jug to force out the last little bit of water. Since its last major explosive eruption (at about 1645 BC) numerous minor and medium-sized, mainly effusive eruptions have occurred. It is a big volcano, which is why it is not surprising that there are many volcanic centers, Solidum adds, referring to the large and long-living edifices on the volcano. The tallest mountain, Kibo, remains dormant and has the potential to erupt again, while Mawenzi and Shira are extinct. The Apolaki Caldera is a volcanic crater with a diameter of 150 kilometers (93mi), making it the world's largest caldera.

The Apolaki Caldera has a diameter of about 150 kilometers, which is more than twice the size of Yellowstone, one of the world's largest calderas. A group of marine scientists has recently discovered a large igneous massif east of the island of Luzon, located at the bottom of the Philippine Sea. It is believed to have formed hundreds of thousands of years ago and has erupted on several occasions in recent geologic time. The gigantic caldera has been named Apolaki, which means "giant lord" in Filipino. Apolaki is one of few calderas in the Philippines, a list that includes the Corregidor in Bataan, Mt. 25, signed by President Rodrigo R. Duterte. Gravimetric analysis shows that the Benham Rise, as the submarine mountain massif is named, consists of a nine miles thick layer of magmatic and volcanic rocks. With a rim diameter of 150 kilometers, Apolaki is now the worlds largest known caldera, surpassing Yellowstone, which spans only 60 kilometers across. In a recent interview with CNN, UP MSI researcher Jeffrey Maloles explained that Filipino scientists had all the necessary training and knowledge to conduct high level research.

Its name is from the ancient Filipino God Apolaki, the god of sun and war. The caldera has a diameter of approximately 150 km (93 miles), twice the size of the famous Yellowstone caldera in Wyoming (US).
