  2. Submarine volcano - Wikipedia

    en.wikipedia.org/wiki/Submarine_volcano

    In 2009, a video camera and a hydrophone were floating 1,200 metres (3,900 ft) below sea level in the Pacific Ocean near Samoa, watching and listening as the West Mata Volcano erupted in several ways. Putting video and audio together let researchers learn the sounds made by slow lava bursting and the different noises made by hundreds of gas ...

  3. List of submarine volcanoes - Wikipedia

    en.wikipedia.org/wiki/List_of_submarine_volcanoes

    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.

    At that time the vent of the volcano was below sea level, but frequent eruptions ejected molten lava up to 70 m (230 ft) above sea level, and sulfurous steam plumes up to 500 m (1,600 ft). The team mapped a roughly conical feature rising from 1,100 m (3,600 ft) water depth, with the volcano having a basal diameter of about 8 km (5.0 mi).

  5. Davidson Seamount - Wikipedia

    en.wikipedia.org/wiki/Davidson_Seamount

    A seamount is an underwater volcano; Davidson rises 7,480 ft (2,280 m) above the surrounding ocean floor. Although there are over 30,000 seamounts in the Pacific Ocean alone, only about 0.1% of them have been explored. [4] The aqueous environment of the seamount means that it behaves differently from volcanoes on land.

    [3] [10] The volcano's base at the seafloor is approximately 20 km in diameter, [11] rising roughly 2,000 m towards the sea surface. Before the 2022 eruption, the volcano's caldera was roughly 150 m below sea-level, and had a size of 4 × 2 km. [7] Its northern and southern portions were filled by volcanic deposits from previous eruptions. [7]

    Kamaʻehuakanaloa is a seamount, or underwater volcano, on the flank of Mauna Loa, the Earth's tallest shield volcano. It is the newest volcano produced by the Hawaiʻi hotspot in the extensive Hawaiian–Emperor seamount chain.

  9. Kolumbo - Wikipedia

    en.wikipedia.org/wiki/Kolumbo

    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]
