Volcanic history. Monitor jökulhlaup alerts.
Skaftá is one of Iceland's most historically significant rivers. Its source lies near geothermal cauldrons under the Vatnajökull glacier, making it prone to jökulhlaups—sudden glacial outburst floods that can multiply the river's flow many times over. The river is forever linked to the catastrophic Skaftá Fires of 1783, when the Laki fissure eruption sent lava flowing into its gorge, with consequences felt across the Northern Hemisphere.
