  2. Submarine volcano - Wikipedia

    en.wikipedia.org/wiki/Submarine_volcano

    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 ...

  3. 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.

  4. Seamount - Wikipedia

    en.wikipedia.org/wiki/Seamount

    A seamount is a large submarine landform that rises from the ocean floor without reaching the water surface (), and thus is not an island, islet, or cliff-rock.Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height.

  5. Hawaiian–Emperor seamount chain - Wikipedia

    en.wikipedia.org/wiki/Hawaiian–Emperor_seamount...

    The island of Hawaiʻi is composed of five volcanoes, of which four (Kilauea, Mauna Loa, Hualalai, and Mauna Kea) are active. The island of Maui has one active volcano, Haleakalā. Kamaʻehuakanaloa Seamount continues to grow offshore of Hawaiʻi island, and is the only known volcano in the chain in the submarine pre-shield stage. [3]

  6. 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.

  7. Types of volcanic eruptions - Wikipedia

    en.wikipedia.org/wiki/Types_of_volcanic_eruptions

    Volcanoes known to have Surtseyan activity include: Surtsey, Iceland. The volcano built itself up from depth and emerged above the Atlantic Ocean off the coast of Iceland in 1963. Initial hydrovolcanics were highly explosive, but as the volcano grew, rising lava interacted less with water and more with air, until finally Surtseyan activity ...

  8. Hilina Slump - Wikipedia

    en.wikipedia.org/wiki/Hilina_Slump

    Like the rest, Kīlauea is composed of alternating subaerial and submarine lava flows fractured by cooling joints and interbedded with weaker rock, sediments, and tephra, resulting in what has been characterized as a fractured rock mass. [13] These discontinuities form zones of weakness that lead to slope failure. [14]

  9. Subaqueous volcano - Wikipedia

    en.wikipedia.org/wiki/Subaqueous_volcano

    A subaqueous volcano is a volcano formed from the eruption or flow of magma that occurs under water (as opposed to a subaerial volcanic eruption). [1] Subaqueous volcanic eruptions are significantly more abundant than subaerial eruptions and are estimated to be responsible for 85% of global volcanism by volume.
