    More than 4 700 earthquakes have been detected in the area between Fagradalsfjall and Keilir, Reykjanes Peninsula, Iceland since the start of seismic swarm on July 4, 2023. Ground deformation (GPS) observations show significant movements, indicating magma propagation in the region where earthquakes are highly concentrated. Magma intrusion is close enough to the Earth’s surface that a volcanic eruption could occur without further escalations in seismic activity or ground deformation.

    An intense earthquake swarm that started in the Krýsuvík-Trölladyngja volcanic system on July 30 continues and, according to the latest analysis by the Icelandic Meteorological Office (IMO), the chances of eruption in the area around Fagradalsfjall in the coming days or weeks have increased and are considered significant.
