William Sager, a marine geophysicist from the Department of Earth and Atmospheric Sciences at the University of Houston, began studying Tamu Massif around 1993 at the Texas A&M College of Geosciences. In September 2013, Sager and his team concluded that Tamu Massif is "the biggest single shield volcano ever discovered on Earth".
Mauna Loa is Earth's largest active volcano [1] by both mass and volume. It was historically considered to be the largest volcano on Earth until Tamu Massif was discovered to be larger. [ 4 ] Mauna Loa is a shield volcano with relatively gentle slopes, and a volume estimated at 18,000 cubic miles (75,000 km 3 ), [ 5 ] although its peak is about ...
Map of world's major seamounts. A list of active and extinct submarine volcanoes and seamounts located under the world's oceans. There are estimated to be 40,000 to 55,000 seamounts in the global oceans. [1] Almost all are not well-mapped and many may not have been identified at all. Most are unnamed and unexplored.

The largest amount of activity recorded for the Kamaʻehuakanaloa seamount was a swarm of 4,070 earthquakes between July 16 and August 9, 1996. [3] This series of earthquakes was the largest recorded for any Hawaiian volcano to date in both amount and intensity. Most of the earthquakes had moment magnitudes of less than 3.0. "Several hundred ...

Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. Many submarine volcanoes are located near areas of tectonic plate formation, known as mid-ocean ridges. The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth. [1]
