Strokkur geyser in Iceland

Strokkur geyser—featured in the image—warms up winter in a completely different way. It is a fountain geyser known for its frequent and reliable eruptions. Located in the geothermal area beside the Hvítá River in Iceland, this geyser erupts every 6 to 10 minutes, shooting hot water 14 to 20 metres into the air, sometimes erupting up to 40 metres. The geothermal valley is also home to a variety of geothermal wonders, including bubbling mud pools, steaming fumaroles and other geysers.

The geyser remained active until the early 20th century when an earthquake once again blocked its conduit. In 1963, following recommendations from the Geysir Committee, locals cleared the obstruction from the basin's bottom, restoring its activity. Since then, the geyser has been erupting regularly. There is science behind its eruption—magma beneath the Earth's crust heats groundwater until the pressure builds up, forcing the water explosively to the surface. Strokkur draws visitors from around the world eager to witness its powerful displays.
