Þjórsá Lava
From Wikipedia, the free encyclopedia
The Great Þjórsá Lava (Icelandic: Þjórsárhraunið mikla [ˈθjour̥sˌaur̥ˌr̥œyːnɪð ˈmɪhkla]) is the largest lava flow in Iceland (by both area and volume) and the largest lava flow[1] that is known to have erupted in a single eruption in the Holocene. Þjórsá Lava has a total volume of more than 25 km3 (6.0 cu mi),[2] covering approximately 900 km2 (350 sq mi).[3][4] The Þjórsá Lava does not appear on the surface until 70 km (43 mi) downstream of its identified eruptive area.[3]
