Reykjanes volcano (Iceland) - Smithsonian / USGS Weekly Volcanic Activity Report for 25 March-31 March 2020 (New Activity / Unrest)
There were more than 6,000 earthquakes recorded beneath the Reykjanes peninsula as of 26 March, making this period of unrest the largest seismic crisis ever recorded in this part of the country since digital monitoring started in 1991, according to IMO. The seismicity occurred across three main volcanic systems: Eldey, Reykjanes-Svartsengi, and Krýsuvík. Uplift continued to be detected in the Thorbjorn area totaling about 70-80 mm; the deformation rate was lower than in January and February.

Deformation modeling suggested that recent inflation was caused by a second magmatic intrusion at a depth of 3-4 km in an area W of Thorbjorn, close to the intrusion that occurred at the beginning of the year. GPS data suggested a small deformation pattern detectable over a regional area, far beyond the Thorbjorn area.

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. Read all

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
