Rising Earthquake Activity in Iceland?

Something is definitely happening. Yesterday there was huge swarm in Reykjanes Ridge, on southwestern side of Iceland. And there has been activity around Tjörnes fracture zone on northern side of Iceland. Both spots are directly above the fault line. We haven't found every volcano there, that area is full of unknown volcanoes. One might be at Reykjanes Ridge, but most interesting spot is Tjörnes fracture zone. Earthquake activity has continued over week now, and swarms come in certain intervals: There was earthquake swarm on Saturday from 18:00 to 00:00, on Sunday swarm appeared from 10:00 to 18:00, now earthquake swarm is starting again, it has been going 1 hour already, strongest quake 3.2 magnitude.

I'm not sure if this is volcano activity, or it comes from fault line. There is no known volcano in center of earthquake activity, but many volcanoes are around it. Last time there was underwater eruption during 1868.

There is also minor activity around Katla volcano, but no signs of coming eruption.

On the 14. September 2012 an earthquake swarm started in El Hierro volcano, Canary Islands, Spain. The earthquake swarm is currently ongoing and there have been more then 300 earthquakes already. The earthquake activity is more or less constant at the moment. Since yesterday (16.09.2012) had around 182 earthquakes have taken place during the past 24 hour period (when this is written). The depth of this earthquakes is around 18 to 28 km. But this suggests an new magma intrusion into El Hierro volcano, or at least that magma is on the move inside El Hierro volcano from older sill inside it.

I have been led to believe that earthquakes caused by volcanism are generally shallow.

There was also some earthquakes at Tindfjallajökull volcano. Its very mysterious volcano, there is no info when it last time erupted, possible during Holocene era. Its not very small volcano, caldera is 5km wide.

Tjörnes Fracture Zone is going crazy right now. Strongest earthquake was 4,5 magnitude, and now the area is littered with multiple minor quakes.

I can almost see the harmonics, starting from 16th.


Prepare for eruption!
