The earthquake swarm on Tjörnes Fracture Zone that started on 28-January-2018 continues and on Sunday 4-February-2018 a magnitude 3,1 earthquake took place. Currently the earthquake activity is ongoing.

It is difficult to know for how long this earthquake swarm is going to continue. It might be several more days and up to few weeks more.
Ups and downs in activity, but no sign of calming down, still. Two green stars and some 380 recorded EQs over the last two days.
I am planning new article tomorrow. There is now a risk of a magnitude 5,0 – 6,0 earthquake in the area. I do wonder when it happens, I am not expecting it soon at this point.
