More than 3000 earthquakes have been automatically detected nearby Eldvorp in the Reykjanes/Svartsengi volcanic system in the past week. Since yesterday (15.05), nine earthquakes had magnitude above M3 and two above M4. The largest event had a magnitude of M4.3 occurred on 15.05 at 17:38 UTC. The seismicity is located at a depth between 4 and 6 km. Recent deformation observations (both cGPS and InSAR) identified the onset of a new inflation event west of Thorbjörn likely caused by magma intrusion. Preliminary modelling results indicate the source is located at a depth between 4-5 km. In light of the increased seismic activity and the ongoing deformation in the Reykjanes/Svartsengi volcanic system the aviation color code is elevated from GREEN to YELLOW. The Civil Protection Department of Iceland elevated their alert level to UNCERTAINTY level on 15.05.
