More frequent earthquake swarms expected in Tjörnes Fracture Zone

According to a news on Rú, there is now a risk of more frequent earthquake swarms in Tjörnes Fracture Zone. This is due to the tension that has been building up in Tjörnes Fracture Zone for the past 200 years, with the last large earthquake taking place 37 years ago (Kópasker magnitude 6.5 earthquake in January 1976). This short and small earthquake swarms in TFZ are not going to release the tension that has been building up there for the past 200 years (in some areas), for that too happen. It takes one or more earthquakes that are stronger than magnitude 6.0 to take place before tension starts to drop in the Tjörnes Fracture Zone.

Increased monitoring for volcanoes in Vatnajökull glacier

I did see a short news about increased monitoring for volcanoes (you have zoom in manually, the new web page is a mess and not highly useful as such in my view) in Vatnajökull glacier.

Two new seismometer have been added to the SIL network in Vatnajökull glacier. Making detection of activity in Öræfajökull, Grímsfjall, Bárðarbunga, Esjufjöll and other volcanoes easier and more sensitive. It is going to be interesting to see what this information this new seismometer bring to light when it comes to activity in Vatnajökull glacier volcanoes.
