This is update for TFZ over the past few days. Along with update for earthquake activity in Iceland during the past few days.
Tjörnes Fracture Zone
Earthquake swarm in TFZ continues. In the past days the largest earthquakes have had the magnitude of ML3.2. A second earthquake swarm is also taking place west of the village of Kópasker. That area also had an earthquake with the magnitude of ML3.2. That earthquake swarm is unrelated to the earthquake swarm taking place off north of Siglufjörður village. Earlier today an earthquake with the magnitude 3.8 took place. More earthquakes are expected to take place. This latest earthquake was clearly felt in Siglufjörður village. This earthquake swarm started on 20th of October. So it has been ongoing now for almost two weeks.

Earthquake activity is expected to continue in this part of TFZ. The risk of large earthquake in this area has not yet passed. Most of the earthquakes appears clearly on my geophone in Hvammstangi.
Iceland activity
Other the earthquake activity in TFZ. It has been generally quiet in Iceland. For the past four days there has been really bad winter storm taking place in Iceland. With wind up to 40m/s and wind gust up to 70m/s or more. This means that fewer earthquakes are being detected by the SIL network in Iceland due to increased wind noise. But earthquake activity has been low in Iceland for the past few weeks (besides TFZ). So I am not sure if that changes anything. There is no volcano activity taking place in Iceland at the moment.
