GUNNUHVER GEOTHERMAL FIELD 4K Iceland

Visit to Gunnuhver geothermal field, Reykjanes peninsula, 20 km westwards from the current eruption. Hot water geysers and volcanic degassing. In reality Gunnuhver is a volcano on Reykjanes volcano belt. April 30, 2021. Gunnuhver is the name of an impressive and colourful geothermal field of various mud pools and fumaroles in the southwest part of the Reykjanes Peninsula. It is tied to a fascinating legend of the region. The Reykjanes Peninsula in southwest Iceland is the continuation of the mostly submarine Reykjanes Ridge, a part of the Mid-Atlantic Ridge, on land and reaching from Esja in the north and Hengill in the east to Reykjanestá  cape in the west. A great deal of volcanic activity was occurring in the Reykjanes Peninsula in 2020 and into 2021, after nearly 800 years of inactivity. After the eruption of the Fagradalsfjall volcano on 19 March 2021, National Geographic's experts predicted that this "may mark the start of decades of volcanic activity". The eruption was small leading to a prediction that this volcano was unlikely to threaten "any population centers". --------------------------------------------------------------------------------------------------------------------------------------- The Gunnuhver volcano is located in southwest Iceland , west of the fishing village of Grindavík . This is the central high-temperature area of the Reykjanes volcanic system , which is located on the peninsula of the same name . The high temperature area Gunnuhver Temperatures under the springs are over 300 ° C, making it one of the hottest spots in southwest Iceland, literally. In the high temperature area there are mud springs and fumaroles . However, the water to be observed is rainwater, without this the area would be dry. On the other hand, under the high-temperature area, there is pure salty seawater in crevices and caves. Volcanic activity continues in this and other volcanic systems on the ocean floor, i.e. H. on the part of the Mid-Atlantic Ridge that rises towards Iceland and is called the Reykjanes Ridge . The last detectable eruption in the Reykjanes volcanic system took place at submarine eruption sites on the Reykjanes Ridge southeast of Eldey in 1926. Recent developments in high-temperature region The volcano has become more active since 2006. An access road had to be closed in 2008 because a new source of clay had come into action in the middle of the way. In addition, Gunnuhver sometimes has small slag outbreaks and hurls hot bits of clay 2 to 4 m high into the air. Such changes and outbreaks were also observed at the Gunnuhver in 1905 and 1967. There were also explosions in the source, so that the area was temporarily cordoned off. Since the source is unpredictable and you don't know how far the very hot bits of clay will be thrown, it is highly recommended to keep yourself at a safe distance. In addition, similar activities at a mud source on Kleifarvatn have already led to an explosion in which glowing bits of clay flew several hundred meters through the air (see Krýsuvík ). Since 2008 the development of a crater can be followed in this area, as can be clearly seen in the pictures from August 2008 . After being closed for several years, the area has been partially accessible again since summer 2010. Geothermal power plant Suðurnes The energy of the volcanic system is used in a geothermal power plant, the Suðurnes power plant. In addition, the salt water that has penetrated caves and heated by the volcano is used in a factory. The series of craters of the Eldvbod also belongs to the Reykjanesystem. There is another high temperature area that is also used by the Suðurnes power plant. Naming The name of the high-temperature area Gunnuhver is related to the legend of a ghost named Gunna (actually Guðrún Önundardóttir). This ghost was haunted here and played tricks on people like z. B. hiding their cattle. Finally, the pastor, Eiríkur Magnússon, succeeded in capturing the spirit in the hot spring, which was then given the name Gunna. --------------------------------------------------------------------------------------------------------------- Info source: Wikipedia #Gunnuhver #VolcanoZone #GeothermalArea
