The world's largest volcano lurks beneath the Pacific Ocean, researchers announced in the journal Nature Geoscience. Called the Tamu Massif, the enormous mound dwarfs the previous record holder ...

The largest volcano on Earth, known as the Tamu Massif, is sitting under the Pacific Ocean about 1,000 miles east of Japan, according to a new study by geoscientists at the University of Houston.

The biggest single volcano on Earth is in the Pacific Ocean, roughly halfway between Hawaii and Japan. Dubbed 'Tamu Massif,' the humongous volcano erupted almost 150 million years ago.

Global warming is driven by under-sea volcanoes; hot, 40,000-mile-long mid-ocean mountain ridges and rifts, ocean currents, and the amount of sunlight penetrating Earth’s surface.

The volcano is thousands of feet below the ocean’s surface, so it poses no danger to people. But under all that water, a dramatic eruption is brewing.

Magma moving under active volcanoes can cause similar opening and closing of fracture systems resulting in changes in the velocity at which ocean noise signals travel through a volcano.

The magma movement beneath the planet’s crust could be the early stages of a new ocean basin formation, which could slowly ...
