Overview of the earthquake activity in Iceland of the last few days

Over the past few days it has been quiet in Iceland. There hasn’t been overall lot happening. Biggest earthquake activity that is currently taking place is happening around 340 km north of Kolbeinsey Island (it’s a tiny Island, with nothing on it, not even birds make use of it).

Largest earthquake have had the magnitude around 3,3.

Bárðarbunga volcano

Currently there isn’t much happening earthquake wise in Bárðarbunga volcano. Current earthquake activity has however exposed the ring fault in the caldera, suggesting that its moving upward at decent speed (few mm/month). This also means that Bárðarbunga volcano is inflating as is.

Deep earthquake activity is also around Trölladyngja (shield volcano). This deep earthquake under Trölladyngja is unusual and that is my view eruption might happen there soon. It is impossible to know when such a event happens.

Katla volcano

Earthquake activity in Katla volcano has been quiet. It is normal that earthquake activity drops in Katla volcano this time of the year. I’m expecting quiet few weeks in Katla volcano.


There is little earthquake activity in Katla volcano at the moment. Copyright of this image belongs to Icelandic Met Office.

Hekla volcano

Two earthquakes appeared in Hekla volcano on 8-December-2016. No other activity happened after that.

Reykjanes ridge

A minor earthquake swarm took place on the Reykjanes ridge on 8-December-2016. Largest earthquake in this swarm had the magnitude of 2,9.

I think this is most of the earthquake activity that has happened in and around Iceland during the last few days. Due to software problems on my server and on my desktop computer I was unable to write an update about what was happening in earthquake activity for the past few days.

Two earthquakes larger then magnitude 3,0 close to Jan Mayen

Today (1-September-2015) two earthquakes happened close to Jan Mayen (around 360 km away from Iceland). Those earthquakes are possibly part of larger swarm in the area, but due to distance from Iceland Met Office seismic network it is difficult to know for sure. I didn’t find any information about those earthquakes in the NORSAR seismic array information system.

Those earthquakes had the magnitude of 3,3 and 3,5. Depth is uncertain due to the distance from SIL network. Smaller earthquakes from this swarm are not detected by the NORSAR (Norway) or the SIL network (Iceland) due to distance from seismometers at both locations. There is no populated area close to the source of this area (closer then 100 km).

Update on the missing person case

Body of the person that was found two weeks ago in east Iceland has been identified. More information can be found here.
