Tamu Massif is a seamount in the northwest Pacific Ocean, [3] sitting atop a triple junction of mid-ocean ridges. [1] Tamu Massif is located in the Shatsky Rise about ...
The TAMU Massif at the southern end has an estimated volume of 2,500,000 km 3 (600,000 cu mi) whereas both ORI and Shirshov (136 Ma) attained 700,000 km 3 (170,000 cu mi). Papanin Ridge, the north end of the rise, has a volume of 400,000 km 3 (96,000 cu mi) but was probably emplaced over a longer period (131–124 Ma).
By comparison, from sea floor to peak, Mauna Kea, on Hawaii's Big Island, is the tallest shield volcano on Earth, but it is nowhere near as massive as Pūhāhonu. Another volcano on the Big Island is Mauna Loa ; a 2013 study estimates Mauna Loa's volume at 83,000 cubic kilometres (20,000 cu mi) which is believed to be an overestimate.
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 125 feet (38 m) lower than that of its neighbor, Mauna Kea.

The issue is not "how big is Tamu Massif?". The issue is "what is Tamu Massif?" GeoWriter 22:53, 7 September 2013 (UTC) Abstract of the Sager et al. paper in Nature Geoscience. GeoWriter 23:09, 7 September 2013 (UTC) Well, from reading your comment above it sounds like you doubt the Tamu Massif as the largest volcano on Earth.

A massif is a smaller structural unit than a tectonic plate and is considered the fourth-largest driving force in geomorphology. [ 2 ] The word "massif" originates from French (in which the word also means "massive"), where it is used to refer to a large mountain mass or compact group of connected mountains forming an independent portion of a ...
