Region
Southwest Vatnajökull
Active jökulhlaup zone—check warnings.
Skaftárjökull covers one of the most geothermally active areas beneath Vatnajökull. The Skaftá cauldrons—two large ice depressions formed by geothermal heat—periodically fill with meltwater and drain catastrophically as jökulhlaups down the Skaftá river. These floods occur every 1–3 years, making the Skaftá one of the most frequently flooded glacial rivers in Iceland and a critical area for scientific monitoring.
