Þjórsárhraun

Þjórsárhraun is the result of the greatest lava flow on earth since the end of the last Ice Age. The lava came from an enormous eruption around 6700 B.C., possibly in Heljargjá canyon in the Veiðivötn region, in Iceland's highlands. The lava's extreme temperature and fluidity contributed to its flow being at least 140 kilometers (87 mi) until it was stopped by the waves of the North Atlantic Ocean. The lava is well visible by Stokkseyri and Eyrarbakki's coastline. The great Þjórsárhraun lava is approx. 975 square km (376 sq. miles), and its volume is 25 cubic km (6 cubic miles).
