This earthquake activity is normal for this part of Tjörnes Fracture Zone. It is not possible to know what is going to happen next in this activity if anything and it might just stop.

Earthquake activity is very common in this part of the Tjörnes Fracture Zone and it is now just around one year since a large earthquake swarm took place far west of Grímsey island in June 2020. It is difficult to know of more earthquake activity is going to happen at this location in next few days.

Earthquake activity in the Tjörnes Fracture Zone often starts slowly before increasing. I don’t know if that is going to happen now since this area has been having a lot of earthquake activity in recent months.

Moving Iceland geology to a bigger server
Because of current high traffic to this website I plan on moving it to a slightly larger server in the time between April to June. I am not sure yet when I can afford the change since this is a slightly more expensive option at 79€ a month from current price of 9,5€ a month (I also have other websites here that I won’t move since they get little to no traffic at all). I am also expecting far higher traffic to this website in the future when other Icelandic volcanoes start to go active for a long and short time period.
Yesterday (01-March-2021) at 19:53 UTC an magnitude Mw3,3 earthquake took place north-east of Grímsey island. This might be a new earthquake swarm in this area since earthquake swarms in Tjörnes Fracture Zone often star slowly. Earthquake swarms are common in this part of Iceland.

There is a chance of a stronger earthquake swarm in this area. Currently the activity remains small and nothing more might happen. This earthquake activity is not connected to what is happening on the Reykjanes peninsula.
Next article about Reykjanes peninsula activity is going to be written tomorrow (2-Mars-2021) unless something major happens.
Since 4-February-2021 an earthquake swarm has been going on east of Grímsey island in the Tjörnes Fracture Zone. This was not a large earthquake swarm, with mostly just earthquakes with magnitude of Mw0,0 to Mw3,0. With largest earthquake taking place on 9-February-2021 at 20:20 UTC with magnitude Mw3,0. After that earthquake activity seems to have slowed down considerable amount.

Earthquake activity is common in this area and in 2020 several large earthquake swarms took place in the Tjörnes Fracture Zone.
Yesterdat (02-December-2020) at 11:38 UTC an small earthquake swarm started on Tjörnes Fracture Zone just south-east of Grímsey island. Largest earthquake in this swarm had a magnitude of Mw3,1. This earthquake swarm was small but there is also a strong snowstorm in Iceland and that has limited detection of earthquakes since late Monday (30-November-2020).

This is a different area from the area that had strongest earthquake swarm in 40 years on Tjörnes Fracture Zone in June 2020 when the largest earthquake had a magnitude of Mw6,0. It is difficult to know if there is going to be more earthquake activity in this area. There is always a risk that is going to happen.
