Short overview of earthquake activity in Iceland

This is a short update of earthquake activity in Iceland on 28-February-2016.

Bárðarbunga volcano

Over the past 48 hours there has been earthquake activity and dyke activity in Bárðarbunga volcano. Some of this earthquake activity has been on around 15km depth. Suggesting magma movements within Bárðarbunga volcano system. Earthquake activity always seems to increase few hours to days after a swarm of deep earthquakes appear in Bárðarbunga volcano.

A dyke activity has appeared on the edge of Bárðarbunga volcano, it is located south-east in the volcano. In a area that has seen this type of dyke activity before. It is interesting that this activity seems to persist at this location.

Tungnafellsjökull volcano

Over the past few days few earthquakes have appeared in Tungnafellsjökull volcano. Some of those earthquakes have had the depth around 15 km. This suggest some type of magma movements inside the volcano, but nothing that suggests that its going to reach the surface any time soon.

Askja volcano

Earlier this week (Week 08) an deep earthquake swarm took place in Askja volcano. With earthquakes having the depth down to around 22 km. Suggesting that magma is flowing into Askja volcano magma chamber at depth. This has been happening at regular basis since 2010. At the moment there is nothing suggesting that eruption is going to happen any time soon in Askja volcano.

Katla volcano

There was some minor earthquake activity in Goðabunga in Katla volcano. This appears to be normal activity for this region of Katla volcano. No other interesting activity took place this week (Week 08) in Katla volcano.

Hekla volcano

Two earthquake where detected in Hekla volcano. Nothing else happened following this earthquake activity. Why this earthquake activity happens remains unclear.

Torfajökull volcano

A minor earthquake activity took place in Torfajökull volcano during the weekend. This activity is possibly due to changes in hyrdrothermal areas in Torfajökull volcano.

Other than this activity things remain quiet in Iceland. There are few minor earthquake swarms on Reykjanes peninsula and Tjörnes Fracture Zone. But they are too small at the moment to write about.


Please remember to support me with donations. The new computer left a big hole in my budget and any support in order to cover it are welcomed. Thanks for the support. 🙂

Move to Denmark

It is now official. I’m moving back to Denmark on 14. April, with just few minor details left to work out (getting a loan for the apartment insurance and few other things). I’ll move into my new apartment on the 15th April. More details later next weeks when I know about the apartment loan.

  1. Wish you the best of luck with your move back to Denmark Jon. I would also like to thank you for your insights – I check your site several times a week and read every update and comments with great interest.

  2. Böðvarshólar geophone station is not updating due to some type of connection failure. I’m going to try and get it start working tomorrow, or hope it start working again on it’s own when the 3G connection improves again.
