Small 2009 hydrothermal explosion in Biscuit Basin, Yellowstone National Park. Hydrothermal explosions occur when superheated water trapped below the surface of the Earth rapidly converts from liquid to steam, violently disrupting the confining rock. Boiling water, steam, mud, and rock fragments are ejected over an area of a few meters up to ...
A phreatic eruption, also called a phreatic explosion, ultravulcanian eruption or steam-blast eruption, [1] occurs when magma heats ground water or surface water. The extreme temperature of the magma (anywhere from 500 to 1,170 °C (930 to 2,100 °F)) causes near-instantaneous evaporation of water to steam , resulting in an explosion of steam ...
An explosion 13,800 years ago left a 5 km (3.1 mi) diameter crater at Mary Bay on the edge of Yellowstone Lake (located in the center of the caldera). [89] Currently, volcanic activity is exhibited via numerous geothermal vents scattered throughout the region, including the famous Old Faithful Geyser , plus recorded ground-swelling indicating ...
On occasion they get much bigger: The largest known crater from a hydrothermal explosion on Earth is in Yellowstone and measures 1.5 miles (2.4 kilometers) across, Poland said.
Earliest known life forms – Putative fossilized microorganisms found near hydrothermal vents; Hot spring – Spring produced by the emergence of geothermally heated groundwater; Hydrothermal explosion – Explosion of superheated ground water converting to steam; Ice volcano – Wave-driven mound of ice formed on terrestrial lakes; List of ...
The hydrothermal vents are recognized as a type of chemosynthetic based ecosystems (CBE) where primary productivity is fuelled by chemical compounds as energy sources instead of light (chemoautotrophy). [28] Hydrothermal vent communities are able to sustain such vast amounts of life because vent organisms depend on chemosynthetic bacteria for food.
An area of Yellowstone National Park that saw a hydrothermal explosion that launched steam and debris into the air Tuesday will be closed for the rest of the season because more blasts may occur, ...
An unusually large eruption of a geyser at Yellowstone National Park's Biscuit Basin occurred Tuesday, sending parkgoers running for cover.
