Volcanic Iceland: Earthquake with magnitude M 5,2 in Þorbjörn mountain (Fagradalsfjall mountain)!!!p1492

Don’t know what I was looking at because all the quakes I saw last night are gone.

Fresh minor earthquake swarm in Öræfajökull volcano
Posted on August 24, 2018 by Jón Frímann

Yesterday (23-August-2018) an fresh earthquake swarm started in Öræfajökull volcano. This earthquake swarm seems to be progressing in the same way as earlier earthquake swarms. Earthquake activity in Öræfajökull volcano only happens when magma is on the move inside the volcano.


Largest earthquake in this swarm had a magnitude of 2,2 and the second largest earthquake had a magnitude of 1,9. Other earthquake activity has been as before and is mostly made of earthquake with magnitude 0,0 and up to magnitude 1,0. The magma in Öræfajökull volcano is slow moving and that is reflected in current earthquake activity.

The gas in the magma is going to decompress. The result is going to be explosive eruption with all the problems that brings. This is not going to be a normal Icelandic lava eruption. When it happens it is not going to be tourist friendly in any way.

Well, it’s not a background type of setting. Per the Smithsonian’s Global Volcanism Program in July:

“After a series of meetings between the Icelandic Meteorological Office, the University of Iceland, and Iceland Geosurvey, the Iceland Department of Civil Protection and Emergency Management stated on 13 July that Öræfajökull has shown clear signs of unrest for at least the past year and a half. The report noted ongoing inflation and increased seismicity, despite a decrease in geothermal activity since December 2017. The volume change since the beginning of the unrest was about 10 million cubic meters, likely from an injection of new magma.”

Thanks for your updates, Jon. I liked coverage of the big landslide earlier this year, too.

Looks like a mag 4+, a couple of upper mag 2's, and a couple smaller just happened...

"THEY" just lowered the strongest EQ by a FULL POINT! From a 4.3 (+/-), to a low 3.

Magnitude 4,6 earthquake in Bárðarbunga volcano
Posted on October 23, 2018 by Jón Frímann

At 00:08 UTC on 23-October-2018 a magnitude 4,6 earthquake took place in Bárðarbunga volcano. This is the strongest earthquake in Bárðarbunga volcano for at least three months. A second earthquake with a magnitude of 3,5 happened at 00:12 UTC. This earthquake activity had earlier smaller earthquakes happening in Bárðarbunga volcano. It started yesterday (22-October-2018) with few minor earthquakes.

Other earthquakes in this earthquake activity were smaller in magnitude. This type of earthquake activity in Bárðarbunga volcano is now common after the end of the eruption in 2015.

During my morning check of the Icelandic MET today, I noticed the two strong EQs at Bard. Wow!

Is the instument package available? The original one? Or has it sunk too far down to get a signal out? Have they replaced it with a new monitoring 'station'? (measured among other the deepening/collapse of the caldera)

Wasn't there a significant quake in the Arctic Circle a few days ago? Just my 2 pence..

Yes. When there are big quakes and swarms in the ridge on north or south we see more quakes on Iceland...

Take Care Luis. Been an A.C. on here for many a year. Always appreciated your informative threads. Think I've told you that before, as an A.C. Thanks for all that you do :) :hf:

And now this...
