Earthquake swarm close to Hveragerði (South Icelandic Seismic Zone)

Today (10-Januar-2020) at 13:10 UTC a earthquake with the magnitude of Mw3,9 took place just 4,9 km outside of Hveragerði town in south Iceland. This earthquake was felt over a wide area. Several small aftershocks have taken place following the first earthquake.

It is unclear if this earthquake is a foreshock or just normal earthquake for this area. Its been 12 years since two Mw6,3 earthquakes (May 2008) took place in SISZ and the shortest time between earthquakes of this size on SISZ is around 10 to 13 years.

Currently my geophones are offline due to technical issues that I am going to fix in March after I have moved back to Iceland.
