Active 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.
What exactly is a geyser? The word derives from the Icelandic verb gjósa, which means “to erupt”. They are no more or less than hot springs that periodically emit a jet of hot water, accompanied by steam. Why is this happening? Geysers have a particular structure, distinct from that of other thermal sources, the opening to the surface is connected to one or more tunnels connecting to underground aquifers. There, the water comes into contact with rocks heated by the magma flowing underground, which causes the water to increase its temperature to reach the boiling point and to come out of the opening.
Best and famous geyser in Iceland
There are two very famous geysers in Iceland, Strokkur and the Great Geysir, both in the geothermal area of Haukadalur, just 120 kilometers northeast of Reykjavík.
Strokkur geyser tour
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.
Great Geysir tour
In Iceland is located Geysir, who is considered the father of the geysers and who curiously gives name to this curious geological phenomenon, and to the geothermal area where it is located. The area of Geysir is one of the best known in Iceland and is very close to Þingvellir by car. From Reykjavík there are lots of bus tours, so you have it easy to contemplate these wonders. As one of the most famous attractions in the country, Geysir has a small hotel, a café, car parks, a souvenir shop, bathrooms and so on. The geysers and the pools are fenced and are all ready for travelers to visit. But don't think it's crowded. In Iceland nothing is crowded. 400 meters north of Strokkur, lies the Great Geysir, which can catapult the water up to 80 meters. The bad thing is that it is a little more lazy than your partner and it takes years without erupt.
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.
But as the best thing is that you see it with your own eyes, in what you are buying tickets to Iceland, we leave you a video of Strokkur in action. It's a wonder to travel to Iceland and pay a visit to Geysir, the father of the geisers. Phenomena like these can only be seen in certain areas of the world, so they are a gift to the eye.
