Over the last few days there has been small earthquake swarm activity in Tjörnes Fracture Zone. The activity has been in two locations, west of Kópasker village and east of Grímsey island (ongoing swarm). Both earthquake swarms are small for now and only few earthquakes larger than magnitude 2,0 have happened. Total number of earthquakes is around 146 for the whole Tjörnes Fracture Zone when this article is written.

The earthquake swarm east of Grímsey island is not over as it has not yet peaked based on what I am seeing. It is more difficult to know about the earthquake swarm west of Kópasker village. As of writing of this article both earthquake swarms are ongoing.

Please remember to support my work. It helps me and prevents me from going broke and deal with hosting costs. Please note that if you donate with bank that I’ve once again updated the bank address because I am going to be moving back to Denmark next year. This is a change from my originals plans, but that is just life. I posted an explanation in a comment here. Thanks for the support. 🙂

Its well over 380 and counting!!
This earthquake swarm continues and there is no sign of it stopping. I am expecting more stronger earthquakes as this earthquake swarm continues.
Largest earthquake in this are had a magnitude of 6,3 in 1976 (14th January) following the eruption in Krafla volcano.

It looks like that we’re about to see something similar to last year’s earthquake swarm in TFZ. Looks like a magnitude 4 just happened there.
We now have a 4.3 just 4km west of Kópasker. The swarm continues and is intensifying.
Green stars now in triplicate and very rapid succession.
