A sudden reduction in pressure causes a rapid phase transition from liquid to steam, resulting in an explosion of water and rock debris. [2] During the last Ice Age, many hydrothermal explosions were triggered by the release of pressure as glaciers receded. [3] Other causes are seismic activity, erosion, or hydraulic fracturing. [4]
Due to its eruption frequency, online photos and videos of Strokkur are regularly mislabelled as depicting Geysir. There are around thirty much smaller geysers and hot pools in the area, including one called Litli Geysir ('Little Geysir'). [31] Detailed thermal mapping of the geothermal field has revealed 364 distinct hot areas. [32]
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.
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.

Cold water geysers are created by a buildup of carbon dioxide which causes the geyser to erupt. The main article for this category is cold-water geyser . Pages in category "Cold water geysers"
