Steam plumes, newly formed after a May 2008 earthquake, rise from the Reykir ("smokes" in Icelandic) geothermal area, with the town of Hveragerdi in the background. The Hveragerdi geothermal field lies within the small Pleistocene Grensdalur volcanic system, the oldest of three volcanic systems in the Hengill area. The geothermal field include fumaroles, hot springs and pools, mud pots, and geysers, and provides heat to the town of Hveragerdi.
