Today (24-July-2019) at 00:55 UTC an earthquake with the magnitude of 4,3 took place 20 km north-north-west of Siglufjörður village. The magnitude of the earthquake was downgraded from Mw4,6 to Mw4,3. This earthquake was felt over a wide area and minor damage was reported in Siglufjörður village, it was just items fallen off shelf. Largest aftershock had a magnitude of 2,7. There have been no major aftershocks at the writing of this article. This area had a earthquake swarm in 2012 with at least one earthquake with magnitude of Mw5,6 and one with magnitude of Mw5,5.
There is a chance that a earthquake activity is increasing in Tjörnes Fracture Zone overall. Since its been a while since it had a major earthquake activity. With that I mean earthquakes with magnitude above Mw6,0.
