  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.

  4. Tamu Massif - Wikipedia

    en.wikipedia.org/wiki/Tamu_Massif

    In 2015, researchers found that the volcano's structure bore patterns of magnetic striping on either side, indicating that the volcano is likely a hybrid of a mid-ocean ridge and a shield volcano. Geologic data also indicated that Tamu Massif formed at the junction of three mid-ocean ridges, which was a highly unusual occurrence.

  6. Submarine eruption - Wikipedia

    en.wikipedia.org/wiki/Submarine_eruption

    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.

  7. Kamaʻehuakanaloa Seamount - Wikipedia

    en.wikipedia.org/wiki/Kamaʻehuakanaloa_Seamount

    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.

  8. 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.

  9. Kavachi - Wikipedia

    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).
