On 20 February an earthquake swarm started 10 km N of Gjögurtá. Over 200 earthquakes were detected by the seismic network with magnitude below M 3.0.
Earthquake swarms are not unusual in the area.

Reykjanes volcano (Reykjanes peninsula (SW Iceland)) activity update: Alert level raised to Yellow- earthquake swarm, inflation
Monday, Jan 27, 2020
IMO reports: An inflation has been detected since January 21st and is centred just west of Mt. Thorbjorn on Reykjanes peninsula. The inflation is unusually rapid, around 3-4 mm per day and has accumulated to 2 cm to date. It has been detected both on continuous GPS stations and in InSAR images. The inflation is most likely a sign of magma accumulation at a depth of just a few km. If magma accumulation is causing the inflation, the accumulation is very small, with the first volume estimate is around 1 million cubic meters. ... [more]

A shallow (10 km) magnitude 4.8 earthquake with many pre- and aftershocks (or a seismic swarm) occurred this morning (Sun) at 07:34 UTC at the SW tip of the Reykjanes peninsula, on the SW active rift zone. The swarm of earthquakes included several quakes of magnitude 3 and higher. The strongest earthquake was widely felt in SE Iceland. ... [more]
