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.
Today, the eastern boundary of the Tonga plate is one of the fastest subduction zones, with a rate up to 24 cm/year (9.4 in/year). [1] The trench formed between the Tonga–Kermadec and Pacific plates is also home to the second deepest trench in the world, at about 10,800 m, [2] as well as the longest chain of submerged volcanoes.

The Tonga–Kermadec Ridge is an oceanic ridge in the south-west Pacific Ocean underlying the Tonga–Kermadec island arc.It is a result of the most linear, fastest converging, and seismically active subduction boundary on Earth, the Kermadec–Tonga subduction zone, and consequently has the highest density of submarine volcanoes.
In 2015, a new island was formed as a result of a month-long eruption of a submarine volcano off the coast of Tonga. Of about 1,500 active volcanos in the world, 111 are in Japan, which sits on ...
