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]
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.
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.
Then, they found a new volcano-like formation deep in the ocean waters. The new volcano-like structure sits more than 1,600 meters from the water's surface. So, it's far too deep to pose a danger ...
Researchers recently discovered a mud volcano near the Norwegian island of Bjørnøya, or Bear Island, in the Arctic waters of the Barents Sea. 'Unique' underwater volcano discovered in the Arctic ...

Since 1981, they spent nearly 9,000 hours underwater around the Pacific Ocean. [8] HURL has facilitated the long-term study of the Lo’ihi submarine volcano since 1987 and has analyzed its unique ecosystem and documented the growth of this new Hawaiian Island including investigation the collapse event in 1996.
Davidson Seamount was the first underwater volcano to be classified as "seamount" by the United States Board of Geographic Names, in 1938, and was named in honor of the United States Coast and Geodetic Survey scientist George Davidson, one of the key figures in the survey of America's west coast.
