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.

Geysir, a geyser in Iceland, after which the phenomenon is named. [5] 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 ...
Strokkur (Icelandic [ˈstrɔhkʏr̥], "churn") is a fountain-type geyser located in a geothermal area beside the Hvítá River in Iceland in the southwest part of the country, east of Reykjavík. [1] It typically erupts every 6–10 minutes. [2] Its usual height is 15–20 metres (49–66 ft), although it can sometimes erupt up to 40 metres ...
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 ...
Andernach Geyser, (Germany), the world's highest cold-water geyser Herľany, (Slovakia), first eruption in 1870. Cold-water geysers are geysers that have eruptions whose water spurts are propelled by CO 2 bubbles, instead of the hot steam which drives the more familiar hot-water geysers: The gush of a cold-water geyser is identical to the spurt from a freshly-opened bottle of soda pop.
Grey Bulger Geyser is a single geyser, which erupts out of multiple vents, which depending on the seasonal water table, erupt either continuously or intermittently. The two largest vents often reach about 2 feet (0.61 m) but sometimes surge to 6 feet (1.8 m).
The first recorded eruption of Opal Pool was in 1947, recurring in 1949, 1952 and 1953, then ceasing. Eruptions resumed in 1979, happening at least once in most following years. Eruption heights are typically under 30 feet (9.1 m) in height, but some eruptions have been seen with heights of 70 feet (21 m) to 80 feet (24 m).
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]
