The pressurized water boils, and this causes the geyser effect of hot water and steam spraying out of the geyser's surface vent. A geyser's eruptive activity may change or cease due to ongoing deposition of minerals within their plumbing, exchange of functions with nearby hot springs, earthquake influences, and human intervention.

During the 1880s, Excelsior Geyser in Midway Geyser Basin was known for significant hydrothermal explosions. [7] Other explosions have been linked to seismic events, such as during the 1959 Hebgen Lake earthquake , [ 8 ] while others are linked to changes in plumbing below geysers or hot springs, such as the 1989 explosion at Porkchop Geyser in ...
Geysers are the most well known hydrothermal feature. [ citation needed ] They occur when groundwater in underground cavities becomes superheated under a lid of colder surface water. When the superheated water breaches the surface, it flashes to steam, causing the pressure below it to suddenly drop, which causes a chain reaction where most of ...
A surprise eruption of steam in a Yellowstone National Park geyser basin that sent people scrambling for safety as basketball-sized rocks flew overhead has highlighted a little-known hazard that ...
Riverside Geyser is a geyser in Yellowstone National Park in the U.S. state of Wyoming. The geyser is located on the Firehole River within the Upper Geyser Basin. The geyser shoots steam and water to heights of 75 feet (23 m) in an arch over the river, sometimes causing rainbows. The eruptions occur every 5 1 ⁄ 2 to 7 hours.

The nearby geyser Strokkur erupts much more frequently than Geysir, erupting to heights of up to 35 metres (115 ft) every few minutes. [14] Strokkur was first described in 1789. [ 4 ] There is contrast in its lack of warning of eruption with the case of Geysir and evidence that the plumbing might not be totally independent. [ 12 ]
Reports say that this volcanic eruption could trigger an ice age from the sheet of ash that not even the sun could stand a chance of penetrating. 'High threat' supervolcano could bring about an ...
