Mt Thorbjorn volcano (Reykjanes peninsula, Iceland): renewed inflation
The Icelandic Meteorological Office (IMO) report that the inflation and associated uplift that occurred around Mt Thorbjorn volcano in January-February has started again. The deformation is occurring in the same location as before, but at a slower rate. The uplift started in January but paused temporarily at the end of February. The IMO suggest that since the beginning of March, the uplift is about 20 mm. The deformation is believed to be caused by continued magma accumulation at depth. The head of the National Hazard Monitoring Group at the IMO explains that these events doesn't not guarantee that there will be an eruption any time soon.

Significant earthquake activity followed the deformation, with a magnitude 4.6 earthquake on March 12 occurring about 2 km east of the Blue Lagoon and was widely felt in the southwest of Iceland. Several aftershocks followed.

The Icelandic Met Office (IMO) recorded an earthquake with magnitude M 5.2 occurred about 5 km NE of Grindavík. Multiple aftershocks have been detected. The earthquake is the largest earthquake detected on the Reykjanes peninsula since October 2013 when an earthquake of magnitude M 5.2 occurred close to Reykjanestá. The earthquake was felt in large areas of SW-Iceland. ... Read all

Reykjanes volcano (Iceland) - Smithsonian / USGS Weekly Volcanic Activity Report for 11 March-17 March 2020 (Continuing Activity)
On 18 March IMO raised the Aviation Color Code for Reykjanes to Yellow noting that recent InSAR and GPS data indicated that during the second week of March deformation had restarted. The uplift was concentrated in the same place as that recorded in January-February, though at a slower rate. The cause of the deformation was likely an intrusion of magma at 4.5 km depth. ... Read all
