Seltún - the colourful Geothermal Area at Krýsuvík on the Reykjanesskagi Peninsula. The hot springs area contains solfataras, bubbling mud pools, fumaroles, hot springs and warm springs. The high sulphur content of the springs give them a characteristic yellow-orange color. Sulfur was mined at this location until the 1880s. An explosion caused by nearby drilling took place in 1999 that opened up a large crater vent. In 2010 and 2019 other explosions took place, spewing hot mud, water and steam over the area.[1] A boardwalk with viewing platforms has been constructed over the area.
