Iceland - Volcanic unrest (ECHO 13 Nov 2023)Mon, 13 Nov 2023 11:29

  • Since 25 October, intense seismic activity related to a magma intrusion has started in the Reykjanes peninsula in south-western Iceland.
  • As of 12 November around 1,000 earthquakes - all below 3.0 M - have been recorded in the area of unrest. Most of the earthquakes are located in the region north of Grindavik Town, Reykjanes peninsula. The earthquakes are at a depth of 3-5 km corresponding to the lower part of the dyke intrusion. In addition, superficial deformation associated with the magma intrusion has been recorded in the area, this can be an indication that magma is moving closer to the surface.
  • Following this kind of activity, the civil protection has preventively evacuated all the people living in Grindavik Town, almost 3,700 residents and closed all the routes to the town. Moreover, the quakes and ground deformation caused by the magma intrusion resulted in damage to roads and buildings in Grindavik and its surroundings.
  • National authorities are continuously monitoring the area.
