High-temperature areas

Iceland's high-temperature areas number 25 to 40 depending on how they are counted, of which 5–6 lie beneath glaciers.

Principal high-temperature areas

  • Reykjanes
  • Krýsuvík / Trölladyngja
  • Brennisteinsfjöll
  • Hengill
  • Torfajökull
  • Hágöngur
  • Vonarskarð
  • Námafjall
  • Krafla
  • Þeistareykir

The boundaries between high-temperature areas are not always sharp. The Hengill area, for instance, is sometimes treated as one large field spanning Nesjavellir, Innstidalur, Kolviðarhóll, Hveradalir, Hverahlíð, Ölkelduháls and Grændalur.
