IT'S LIKE A 6 TO 8 PACK GOIN ESP IF WE COUNT THAT UNDER WATE SEA MOUNT THINGY OFF TH EOREGON COAST...

Thank you for keeping us updated, Luis! Glad that things are quiet, but they sure can change quickly!

Hekla is rumbling a bit, enough for IMO to contact both aviation control and civil defence.

New equipment has been installed around the Volcano in recent years so there is increased sensitivity in detecting these small quakes, but according to IMO the number of quakes is unusual. They can't say an eruption in imminent but with Hekla things can change in just a few hours.

Keep an eye on the borehole strain in the following link. If it goes up, then eruption will follow in a matter of hours.

Thank you very much my friend!

I've been afraid these would start to act up this year...
Thanks for the updates, Luisport! I'll bookmark & keep up with everything again.

something's brewing on eastern Tjörnes Fracture Zone!

Specialist remark
The earthquake swarm, that started the 7th of November just east of Askja volcano, is still ongoing. This morning (13.11) at 7:30 an event of M3.1 occurred east of Askja. Around 1200 earthquakes have been recorded in the area since the swarm started. The largest earthquake was M3.4 and occurred on the 9th of November. No volcanic tremor and deformation have been detected in the area. This swarm is likely due to tectonic activity. Earthquake swarms occur regularly around Herðubreið and Askja. IMO is monitoring the activity 24/7.

Specialist remark:
The seismic activity east of Askja, that began on November 7th, has been decreasing since wednesday night (13.11) but it is still not over. Around 1200 earthquakes have been recorded in the area since the swarm started, with three earthquakes larger than M3. No volcanic tremor has been detected in the area and no deformation is currently ongoing. This swarm is likely due to tectonic activity. Earthquake swarms occur regularly around Herðubreið and Askja, however the current activity is so far, the largest swarm measured in this area. IMO is monitoring the activity 24/7.

Strong earthquake swarm in Reykjanes volcano

I don’t have a lot of information about what is going on. The area that has having earthquake swarm is located at Geirfugladrangi good 20 to 40 km off the coastline. This earthquake swarm is strong and might even get stronger. I don’t know yet if this earthquake swarm is due to tectonic forces or because magma has started pushing to upper levels in the crust. There are no clear signs of eruption happening at this location at the writing of this article. The volcano in this area is called Reykjanes.

This activity appears to be moving quickly and there’s a lot going on and information in this article is going to get outdated quickly.

Specialist remark

An earthquake swarm started this morning on Reykjanes ridge, around noon few earthquakes > M3.0 were detected. The largest earthquakes of swarm was M4.5 at 13:17. The swarm is located 45 km SW of Reykjanes. Tens of smaller earthquakes have been detected since noon and the swarm continues. The IMO has received reports of the earthquakes being felt in Reykjanes peninsula, the capital area and Akranes. Earthquakes of similar magnitude were last recorded in June 2018 and an intense swarm occurred in the same area in June and July 2015, then the largest earthquakes was M5.0
