Glacial outburst flood at Grímsvötn volcano, Iceland
Seismic readings indicated the onset of a glacial outburst flood from Grímsvötn volcano on January 13, 2025. Grímsvatn floods have occurred almost annually since November 2021. There are examples of volcanic eruptions occurring due to pressure relief in Grímsvötn after water gushes from there. However, glacial outburst floods have occurred much more frequently without volcanic eruptions.
