A powerful earthquake swarm started in the NW part of Bárðarbunga caldera, Iceland at 06:08 UTC on January 14, 2025. Initial data indicate that dozens of quakes occurred in rapid succession, hinting at possible volcanic or tectonic unrest deep beneath the ice. The current activity may be similar to the beginning of the swarm that occurred before the 2014 Holuhraun eruption.
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.
