The Icelandic Met Office (IMO) recorded an earthquake with magnitude M 2.3 at 00:49 local time occurred in Grindavík area.

Seismic activity is still ongoing on Reykjanes peninsula but number of earthquakes has decreased significantly in recent weeks. This seismic activity is due to deformation in the area but the most likely explanation of the deformation are magmatic intrusions. Since mid April there has no uplift been detected around Mt. Þorbjörn but minor ground deformation is still being detected over a greater area in Reykjanes peninsula.

Reykjanes volcano (Iceland) - Smithsonian / USGS Weekly Volcanic Activity Report for 29 April-5 May 2020 (Continuing Activity)
IMO reported that uplift detected in the Thorbjorn area decreased in the beginning of April and stopped later in the month. Seismicity, which had occurred across three main volcanic systems: Eldey, Reykjanes-Svartsengi, and Krýsuvík, had significantly decreased. These data indicated that the injection of magma beneath Thorbjorn had stopped, though there were indications of deformation over a larger area. ... Read all

Mt. Thorbjorn volcano (Reykjanes peninsula, Iceland): continued inflation; no significant change in activity since the last update
The Icelandic Met Office (IMO) recorded an earthquake with magnitude M 2.5 at 16:55 local time occurred N of Grindavík. The earthquake was felt in Grindavík. Considerable seismic activity has been ongoing in the area during the last weeks in connection with deformation in the area. The deformation is measured at a slower rate than in January, but still continuing in magma accumulation at depth. The deformation is occurring in the same location as before. Read all
