Geysers in Iceland

The name of all geysers in Iceland and around the world comes from the Great Geysir that erupted in the 14 th century. This geyser used to erupt every 60 minutes till the 20 th century when it finally became dormant. But, because of the earthquakes that occurred in June 2000 the geyser reawakened and it now erupts every 8-10 hours. Another very famous geyser in Iceland is Strokkur. This one erupts every 8 minutes throwing water and steam to a height of approximately 20 meters. Throughout the island there can be found several other smaller geysers that can be either active or dormant. They are usually found in active volcanic areas or even lands that are prone to earthquakes. The thermal springs are considered to be geyser features as being boiling mud pools.

Geyser features

Every one of the geysers in Iceland and around the world has a powerhouse that lies deep in the underground. There the surface water goes through fissures and is collected in caverns. Because of the high temperature of the volcanic rock (around 200 C) the trapped water is heated. Thus, it expands into steam forcing its way up and out. For example, the Great geyser’s column length is of 23 meters. The water erupting from this geyser used to reach the height of 60 meters, but today its maximum is only about 10 meters. Watching geysers in Iceland erupt, no matter how small they are can be a fascinating sight for anyone. In the beginning the water starts boiling, then a bubble forms and bursts as the steam forces its way out being much lighter than the water.
