  2. Underwater explosion - Wikipedia

    en.wikipedia.org/wiki/Underwater_explosion

    An underwater charge explosion, conducted by the US Navy. An underwater explosion (also known as an UNDEX) is a chemical or nuclear explosion that occurs under the surface of a body of water. While useful in anti-ship and submarine warfare, underwater bombs are not as effective against coastal facilities.

    The underwater explosion also sent 146 million tons of water from the South Pacific Ocean into the stratosphere. [59] The amount of water vapor ejected was 10 percent of the stratosphere's typical stock. [60] It was enough to temporarily warm the surface of Earth. It is estimated that an excess of water vapour should remain for 5–10 years. [58]

  4. 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. For example, it is believed that 70 to 80% of the Earth's magma output takes place at mid ...

    Thermal contraction from chilling on contact with water, causing phreatomagmatic eruptions; In terms of activity, there are explosive eruptions and effusive eruptions. The former are characterized by gas-driven explosions that propel magma and tephra. [1] The latter pour out lava without significant explosion. [2]

    An ash plume reached 4.5 km (15,000 ft) on January 13. Officials identified two vents, one on Hunga Haʻapai and another about 100 m (330 ft) offshore and underwater. [36] Large rocks and wet, dense ash were being ejected up to 400 m (1,300 ft) into the air. [36] [37] By 16 January, a new island had been formed by the explosion. [38]

  8. Submarine volcano - Wikipedia

    en.wikipedia.org/wiki/Submarine_volcano

    Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. Many submarine volcanoes are located near areas of tectonic plate formation, known as mid-ocean ridges. The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth. [1]

  9. Volcanic tsunami - Wikipedia

    en.wikipedia.org/wiki/Volcanic_tsunami

    An underwater explosion resulting in the formation of a crater can cause subsequent expansion, rise and gravitational collapse to create tidal bores as well as smaller waves. [3] Most waves caused by underwater volcanic explosions have small amplitudes, an exception being those produced by the 1996 eruption of Karymsky Lake in Russia which ...
