Minor earthquake swarm on Tjörnes Fracture Zone (east of Grímsey island)

Today (25-March-2021) a minor earthquake swarm took place east of Grímsey island. Earthquake swarms are common in this area. Largest earthquake in this swarm had a magnitude of Mw3,0. This earthquake swarm might not be over.

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.
