At noon today, a powerful earthquake series with high microseismic activity began just northeast of Fagradalsfjall, a short distance north of Fagradalshraun. The largest earthquake of the series was measured with a magnitude of 4.0 at 2:03 p.m. The earthquakes are now being measured at a depth of about 5-7 km. Skjálfts have been found in Reykjanesbær, Grindavík, in the Cape Town area and all the way up to Borgarnes. It is believed that these letters are due to a magma flow that is taking place northeast of Fagradalsfjall at a depth of 5-7 km.
Because of the avalanche, there is an increased risk of rock falls. Several earthquakes have already been measured above magnitude 3, and in earthquakes like this, rockslides and even landslides can occur. There have been no reports of recent rock falls in the area yet. If there are more powerful earthquakes, the probability of a rockfall increases. People are advised to be careful on steep slopes, near steep sea cliffs and avoid areas where rocks can collapse. The National Police Commissioner in cooperation with the Suðurnesj Commissioner of Police has declared a level of uncertainty
Civil Defense and VONA notification has been issued and switched to yellow for Krísuvík. The National Weather Service will closely monitor progress.
