This is a update on the earthquake swarm on Tjörnes Fracture Zone. Information in this article might get outdated quickly.
The earthquake swarm is ongoing as of writing of this article, it has now been going for a week. Since Wednesday there haven’t been any earthquakes over magnitude 3,0. Largest earthquake have reached magnitude 2,9 in last 48 hours. Total number of earthquakes in last 48 hours is around 567.

This earthquake swarm has been slowly getting less intense and fewer earthquakes have been recorded since yesterday than the days before. It does not mean that this earthquake swarm is over. It might increase again if a large earthquake happens (magnitude 4,0+).

Jon thanks for the updates. What would you guess is ahead for this area over the next month or so ? Is it likely that a large quake is still possible and would a larger quake have any chance of causing any wave action?
It is not possible to make a prediction on TFZ. The fault line structure in this area is complex and its also larger than SISZ as an example.
I don’t know if you can read this article. It shows in great details the faults in TFZ and their activity in the time period of 1994 – 2005.
