Intense seismic activity continues in the Reykjanes peninsula and it mainly occurs around the Fagradalsfjall area. Since midnight almost 1800 earthquakes have been automatically detected, and about 215 manually were reviewed. Thirty-two earthquakes had magnitude above M3 and five had magnitude above M4. A peak in the seismicity occurred between 02.00-03.00 UTC this night. The latest data from the cGPS network and the InSAR processing (retrieved this morning at 08.00 UTC) indicate that the magma keeps moving slowly SW along a line between Keilir and Fagradalsfjall. No tremor has been detected since the evening of 03.03.2021, when the aviation color code has been changed to orange. Overall the area in between Krýsuvík and Reykjanes-Svartsengi volcanic systems is still showing a very elevated level of activity. However, in light of the current geophysical data an eruption is not considered imminent. IMO keeps monitoring closely the area and surveillance has been (and will be) potentiate in order to improve the capability of detecting signs of imminent eruption and follow any possible evolution.
