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 total number of submarine volcanoes is estimated to be over one million (most are now extinct) of which some 75,000 rise more than 1 kilometre (0.62 miles) above the seabed. [1] Only 119 submarine volcanoes in Earth's oceans and seas are known to have erupted during the last 11,700 years. [2] [3] Hydrothermal vents, sites of abundant ...

Kamaʻehuakanaloa Seamount (formerly Lōʻihi) continues to grow offshore, and is the only known volcano in the chain in the submarine pre-shield stage. [ 1 ] The second part of the chain is composed of the Northwestern Hawaiian Islands , collectively referred to as the Leeward isles , the constituents of which are between 7.2 and 27.7 million ...
Submarine eruptions are volcano eruptions which take place beneath the surface of water. These occur at constructive margins, subduction zones and within tectonic plates due to hotspots . This eruption style is far more prevalent than subaerial activity.
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 meters (9,800 ft) and 6,000 meters (20,000 ft).Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains are among the flattest, smoothest and least explored regions on Earth.

Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height. They are defined by oceanographers as independent features that rise to at least 1,000 m (3,281 ft) above the seafloor, characteristically of conical form.
