The latest cGPS deformation data around the Þorbjörn and Svartengi area confirm that the deformation, which started 27 October, continues. As initially stated, the
ongoing deformation rates are higher than in previous events which occurred in a similar area in 2020 and 2022. Overall, the seismicity north of Grindavík has been declining over the past 24 hours and there are no significant changes in earthquake depths. However, it is important to emphasise that
the current deformation may trigger renewed seismicity in the area that could be felt by people.
New satellite data are expected to be delivered later today, and a new interferogram will be processed as soon as the data are available. The results will allow us to identify and interpret the deformation processes that have occurred on the peninsula
over the past 12 days. We expected to publish the results tomorrow.
An episode of complex volcano-tectonic unrest is currently affecting the Reykjanes Peninsula. It is interpreted to result from
multiple deformation sources at depth, which are interacting and affecting a wide area across the peninsula.
Comment: A airburst like a mini-Tunguska event? The small size of the quake, as opposed to the sound it made would seem to point in that direction.
