Geysers of Iceland

thumb|Strokkur at rest Strokkur (Icelandic , "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. It typically erupts every 6–10 minutes. Its usual height is , although it can sometimes erupt up to high.

Geysir (), sometimes known as The Great Geysir, is a geyser in south-western Iceland, that geological studies suggest started forming about 1150 CE. The English word geyser (a periodically spouting hot spring) derives from Geysir. The name Geysir itself is derived from the Icelandic verb geysa ("to go quickly forward"). Geysir lies in the Haukadalur valley on the slopes of Laugarfjall lava dome, which is also the home to Strokkur geyser about to the south. The Strokkur geyser may be confused with it, and the geothermal field it is in is known usually as either Geysir or Haukadalur.
