Bjarnarflag - Geological disturbances during the Mývatn fires - North East Iceland
Region:
North East
About: (Description)
Bjarnarflag, the area west of Námafjall. Geological disturbances during the My´vatn fires. Many drill holes for steam power, both for the diatomite plant and for an electric station built 1968-69. Capacity of 2,625 kW.
The Krafla eruptions in 1975 and 1977 caused a great deal of disturbance there. The earth baths at My´vatn were opened in 2004. They are open the whole year round. The water from the drill hole at Bjarnarflag that is owned by the National Energy Authority is piped into the bathing lagoons. The water is 130° C hot when it arrives and is treated in a so-called heat exchanger
before it is pumped comfortably hot into the lagoons.
Vapor pressure is utilized to transfer the water into the lagoons via an underground pipe that is approximately 1 km long. Before this can be done the water is first pumped into a gigantic tub next to the lagoons and this tub may actually be considered a new, man-made geyser!
A total of 3.5 million liters of water are contained in the lagoons, i.e. in the bathing lagoon itself and it's safety and draining lagoon. The water temperature in the bathing lagoon is ordinarily 36-40°C. The lagoons are man-made structures with bottoms containing sand and gravel.
The nature of the water is in some aspects very unique. It contains a large amount of minerals, is alkaline and is therefore very suitable for bathing. Because of the mineral content, undesirable bacteria and vegetation do not thrive in the lagoon which makes the use of chlorine or other disinfectant unnecessary.
