The most common places where Geysirs and Iceland hot springs occur is in high-temperature geothermal areas especially within focused areas of volcanism and rifting.
Here temperatures are above 200°C in less than one kilometre depth. The Iceland hot springs form when the temperatures at depth rise above boiling causing the hot springs to erupt in the form of geysirs.
Geysir eruptions take place when the boiling water within the fountain, which is typically hindered by cool water above it, explodes and forces its way to the surface.
The water boils and turns into steam, and because steam occupies a larger volume than water, water in the channel is blown and thrown high up in the air. The Iceland hot springs are amazing to watch and experience!
The natural Great Geysir is a standout amongst the most stunning sights of Iceland. The formation of the Great Geysir was discovered in 1294 when a violent earthquake shook Iceland’s southern lowlands altering the geothermal area in the valley of Haukadalur.
The activity resulted in the formation of the major Iceland hot springs. In 1294, massive earthquakes struck the area increasing the intensity of the thermal area.
The most violent earthquake to hit the area had a magnitude of 6.5 on the Richter scale, and it took place on 17th June 2000. Since then, the area erupts sporadically. Geysirs in this area are known for violently ejecting steaming water to a height of 60-80m.
Strokkur is another geysir that is located close to Great Geysir, less than 100 metres away. Strokkur is among the most stunning and famous fountain geysirs in Iceland. It is a natural geysir that erupts regularly, every 5-9 minutes and spouts steaming water to a height of 20 m.
Smaller geysirs in Iceland can be found in Haukadalur which is located in the south-western Iceland and features miniature geysirs and Iceland hot springs, mineral-rich pools, steaming fumaroles and mud pot formations.
This area has numerous walking paths leading to ancient silica deposits and the hot springs. Hence, a perfect hiking and walking area.
