William Sager

Tamu Massif is an underwater volcano the size of New Mexico in the Shatsky Rise oceanic plateau in the northwestern Pacific Ocean. It could be the largest single volcano on Earth and is comparable in size to the largest known volcano in the Solar System, Olympus Mons on Mars. Data from Tamu Massif document a class of oceanic volcanoes that is distinguished by its size and shape from the thousands of common seamounts found throughout the ocean.

Scientists like William Sager are collecting data on its shape and formation. Sager is a professor of Earth and atmospheric sciences at the University of Houston. His areas of research expertise are marine geophysics, paleomagnetism, and plate tectonics.
