Over 1700 earthquakes have been measured in the Reykjanes Peninsula since midnight, few of which were over M3, the largest one measured M4,6 at 08:53 GMT this morning. As before, the magmatic activity is centered around Mt. Fagradalsfjall southwest of Mt. Keilir.

Yesterday, March 10th, 2500 earthquakes were detected in the Reykjanes Peninsula, 40 of which were over M3, the largest one measuring M5,1 at 3:14 GMT.

Yesterday, the Scientific Advisory Board of the Icelandic Civil Protection met to discuss the latest monitoring results from the seismic unrest on the Reykjanes Peninsula. The main findings of the meeting were:

  • The dike intrusion is expanding with the most active magma flow centered at the southern part of it. A volcanic eruption remains a possibility as magma is still flowing into the corridor. With the ongoing activity the probability of an eruption increases day by day. It is considered very unlikely that lava from a possible eruption would reach populated areas.

  • It is important to follow the activity in the southern region of Mt. Fagradalsfjall in order to evaluate whether the dike is expanding to the south.

  • Latest satellite images and GPS data show that accumulation of magma is concentrated at the southern end of the dike beneath Mt. Fagradalsfjall. This is currently the most likely site for a possible eruption.

  • If the dike keeps expanding and increasing stresses in the area, continuing earthquake activity that can be felt in populated areas is expected.
