About one second after such an explosion, the hot gas bubble collapses because: The water pressure is enormous below 2,000 feet (610 m). The expansion reduces gas pressure, which decreases temperature. Rayleigh–Taylor instability at the gas/water boundary causes "fingers" of water to extend into the bubble, increasing the boundary surface area.
The present-day global methane hydrate reserve was once considered to be between 2,000 and 10,000 Gt C (billions of tons of carbon), but is now estimated between 1500 and 2000 Gt C. [37] However, because the global ocean bottom temperatures were ~6 °C higher than today, which implies a much smaller volume of sediment hosting gas hydrate than ...
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 ...
Bromine gas (Br 2) undergoes an autocatalytic cycle known as the 'bromine explosion', which occurs in the ocean and salt lakes such as the Dead Sea, where a high quantity of salts are exposed to the atmosphere. Bromine contributes to 5-15% of tropospheric ozone layer losses. [1]
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]
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]
The buoyancy from the resulting bubbles lifts the water even higher, releasing yet more bubbles. This process forms a column of gas, at which point the water at the bottom is pulled up by suction, and it too loses CO 2 in a runaway process. This eruption discharges the gas into the air and can displace enough water to form a tsunami.
