Watch an Eruption of a Geyser
The famous Geysir of Iceland is what has given the common name of geyser to these thermal springs and is located in Haukadalur, Iceland. Although a few kilometers away are another type of geysers, this is the most visited and we will talk about throughout the post. The whole area is called "Golden Circle" and is made up of the Gullfoss waterfall, the Haukadalur valley, and the valley and the Thingvellir fault.
To begin with this post, we must define what is a geyser and why it is so striking for tourists. In principle, a geyser is a special type of thermal source that periodically emits a column of hot water and steam into the air. Below what we see on the surface, a natural phenomenon happens that is difficult to find in other parts of the world.
The formation of geysers requires a favorable hydrogeology that exists only in some parts of the planet, so they are a rather strange phenomenon. There are about 1000 around the planet, of which almost half are located in the Yellowstone National Park, United States. Others can also be visited in Argentina, Bolivia, Chile and Russia.
The eruption activity of the geysers can change or cease due to the deposition of minerals within the internal channels of the geyser, when exchanging functions with nearby hot springs, by the influence of earthquakes, or because of human intervention. This effect is caused by the occasional activity between the water that is located on the surface and the rocks heated by the underground magma. They differ from other hot springs, because the geysers contain small openings, where hot underground waters and cold water meet on the surface. That constant contact, generates a pressure from bottom to top, filtering the hot water through the internal ducts, mixing with the steam and resulting in a violent internal boiling and the resulting foam of water and steam, which is expelled outside the geyser. This last, is what we can see in the photos and the part that tourists see who come to this natural phenomenon.
In some parts of the world, such as in Iceland, the duration of eruptions can last seconds and happens every 15 minutes. On the other hand, and especially those located in Yellowstone, United States of America, erupt for 10 minutes and between one and another can go from 8 to 12 hours.
On the way to the famous Geysir, you can see other small geysers such as Litli, Smidur and others, which expel water constantly, almost without stopping, so its height is very small. That path takes you to the star geyser, the one that gets all the attention and that is surrounded by a cordon, for security reasons. It has an average eruption of approximately twice a day. In the surroundings you can see restaurants, cafes and gift shops.
At 400 meters from the great Geysir, the geyser of Strokkur is located, which erupts from every 4 to 8 minutes, for several seconds, with an average height of between 20 to 40 meters.
+ The average height of the Geysir is 80 meters high during the eruption.
+ In the year 2000, it managed to rise to 122 meters in height.
