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.
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 ...
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.
Ahyi Seamount is an active shallow submarine volcano in the Northern Mariana Islands, in the Northwestern Pacific Ocean. It has erupted 5 times since the year 2000; in 2001, 2014, 2022–23, and twice in 2024. [1] Since 2009, it has been a part of Marianas Trench Marine National Monument of the United States.
Kavachi is one of the most active submarine volcanoes in the south-west Pacific Ocean. [1] Located south of Vangunu Island in the Solomon Islands, it is named after a sea god of the New Georgia Group islanders and is also referred to locally as Rejo te Kavachi ("Kavachi's oven"). The volcano has become emergent and then been eroded back into ...
Developments in technology mean that submarine volcanoes can now be studied in greater detail. Despite this progress, understanding is still limited. Mid ocean ridges for example are the most active volcanic systems on Earth but roughly only 5% of their length has been studied in detail. [2]
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 ...
Kolumbo is an active submarine volcano in the Aegean Sea in Greece, about 8 km northeast of Cape Kolumbo, Santorini island. The largest of a line of about twenty submarine volcanic cones extending to the northeast from Santorini, [1] it is about 3 km in diameter with a crater 1.5 km across. [2]
