According to the latest interferometric (InSAR) data from Sentinel-1, the accumulated vertical deformation has amounted 4-4.5 cm from 27 April to 21 May, reflecting continued magma intrusion and migration under the surface.
About 400 quakes have been registered over the past 24 hours with a maximum magnitude of 3.5 that occurred at 07:15 local time today. The earthquake was widely felt on the Reykjanes peninsula and in the capital area located about 3 km northeast of Þorbjörn.
