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 ...
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.
The vents of such geysers are artificial, but are tapped into natural hydrothermal systems. These so-called artificial geysers, technically known as erupting geothermal wells, are not true geysers. Little Old Faithful Geyser, in Calistoga, California, is an example. The geyser erupts from the casing of a well drilled in the late 19th century ...
Other explorers in the region incorrectly assumed that the lake's name was spelled 'heart' because of its shape. The Heart Lake Geyser Basin begins a couple miles from the lake and descends along Witch Creek to the lakeshore. Five groups of hydrothermal features comprise the basin, and all of them contain geysers, although some are dormant. [22]
The hydrothermal explosions are believed to result from clogged passageways in the extensive natural plumbing network under Yellowstone, Poland said. A clog could cause the heated, pressurized ...
Video of the eruption showed people, including children, running as a column of black and gray material and vapor launched into the air. Yellowstone is famed for its thermal features and hot pools.
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 ...
Based on the occurrence of large hydrothermal explosion events over the past 16,000 years, an explosion large enough to create a 100-(meter)- (328-ft-) wide crater might be expected every few ...
