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 most well known is Surtsey in Iceland (1963-1967). [10] Similar island building activity occurs frequently but these are often short lived. [10] Volatile content is also significant. Magma being transported into the ocean through tunnels may see gases being exsolved before reaching the water and so the eruption is effusive.
Littoral explosion at Waikupanaha ocean entry at the big island of Hawaii was caused by the lava entering the ocean. A steam explosion is an explosion caused by violent boiling or flashing of water or ice into steam, occurring when water or ice is either superheated, rapidly heated by fine hot debris produced within it, or heated by the interaction of molten metals (as in a fuel–coolant ...
Lake Nyos, the site of a limnic eruption in 1986. A limnic eruption, also known as a lake overturn, is a very rare type of natural hazard in which dissolved carbon dioxide (CO 2) suddenly erupts from deep lake waters, forming a gas cloud capable of asphyxiating wildlife, livestock, and humans.
Volcanic ash is formed during explosive volcanic eruptions and phreatomagmatic eruptions, [2] and may also be formed during transport in pyroclastic density currents. [3] Explosive eruptions occur when magma decompresses as it rises, allowing dissolved volatiles (dominantly water and carbon dioxide) to exsolve into gas bubbles. [4]
Only pure chemicals belong here not fuel air mixtures to be here a gas must have an upper explosive limit of 100%. Pages in category "Explosive gases" The following 9 pages are in this category, out of 9 total.
For example, the recovery time of ocean heat content of Pinatubo, which caused comparable radiative forcing to Krakatau, seems to be much shorter. This is because Pinatubo happened under a warm and non-stationary background with increasing greenhouse gas forcing. [7] However, its signal still could penetrate down to ~1000 m deep. [1]
Iceland, well known for both glaciers and volcanoes, is often a site of subglacial eruptions. An example an eruption under the Vatnajökull ice cap in 1996, which occurred under an estimated 2,500 ft (762 m) of ice. [61] As part of the search for life on Mars, scientists have suggested that there may be subglacial volcanoes on the red planet.
