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.
Submarine eruptions may produce seamounts, which may break the surface and form volcanic islands. Submarine volcanism is driven by various processes. Volcanoes near plate boundaries and mid-ocean ridges are built by the decompression melting of mantle rock that
Axial Seamount (also Coaxial Seamount or Axial Volcano) is a seamount, submarine volcano, and underwater shield volcano [3] in the Pacific Ocean, located on the Juan de Fuca Ridge, approximately 480 km (298 mi) west of Cannon Beach, Oregon.

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 ...
Submarine volcano approximately 1,300 km south of Tokyo. In October, a large amount of pumice was seen to have been released in this eruption, and washed ashore on Okinawa and Amami Islands.
