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 volcano is a submarine volcano rising to within 24 meters (79 ft) of the sea surface, 3.2 kilometers (2.0 mi) due west of Dequey Island. It is one of the active volcanoes in the Philippines . Eruptions
Didicas Volcano is an active volcanic island in the province of Cagayan in northern Philippines. The island, which was a submarine volcano and re-emerged from the sea in 1952, is 22 kilometres (14 mi) NE of Camiguin Island, one of the Babuyan Islands in Luzon Strait.

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 ...

Ruby Seamount is a stratovolcano with a more shallow southern peak, [5] and is part of the nine volcano Southern Seamount Province of the Mariana Arc, in the Izu–Bonin–Mariana Arc. [ 3 ] : 151 Its location is consistent with it being a back-arc extension associated volcano.
An eruption was recorded around 1857. It was reported as phreatic and possibly partly submarine.. In 1991, there were reports of volcanic activity but instrumental investigations showed no sign of unusual volcanic activity, such as intense fumarolic activity, felt earthquakes, fissuring at the volcano's slopes, or smell of sulphur.
