Strong earthquake swarm ongoing in Skjaldbreið shield volcano

Yesterday (10-12-2017) a earthquake swarm started in Skjaldbreið shield volcano (in Global Volcanism program this area is under Presthnjúkar area). Currently the earthquake swarm is ongoing. This activity started on Friday with few earthquakes and started in full force when the magnitude 3,5 earthquake happened. Largest earthquake so far had the magnitude of 3,8 and was felt as was the first earthquake that happened.

At the moment the number of earthquakes recorded is at 100 and that number is going to increase as this earthquake swarm continues, number of earthquakes happening has dropped considerably for the last few hours. This is the first large earthquake swarm in Skjaldbreið since 1992 according to Icelandic Met Office records (it goes back to 1706 can be viewed here (Icelandic only), locations are not accurate until late 20th century). This earthquake activity appears to be only tectonic in nature and there are no signs of magma movements at the moment.

  2. Interesting deep quake at an interesting place… out in no mans land:

    14.12.2017 23:41:20 64.582 -17.153 18.2 km 0.9 99.0 19.0 km ESE of Bárðarbunga

    1. At this location there is a odd dike intrusion happening based on the earthquake pattern for the last few years. It doesn’t seems to be connected to any central volcano as it looks now.

  3. Hi Jon.

    I have followed your blog for a number of years. Thank you for the informative
    content.

    Recently the blog does not appear to be mobile friendly on my mobile phone?

    The content is too large and I need to scroll around to read it.

    Has anyone else reported this to you?

    1. I have the same problem :/ You can switch to desktop mode, then its all visible. but you need to change it every time you visit here.

    2. I am aware of this problem with mobiles. But there isn’t anything I can do to fix this at the moment since I haven’t found the fix for this problem. The mobile pack I was using with WordPress did go obsolete years ago when it was bought by some company from its original developer. Recent WordPress themes are mobile friendly (for most part) but I don’t like them (as they are dark) and don’t contain the graphic I want to use (header banners).

      I will find solution one day to this problem but until then my website is going to be unfriendly to mobile phone screens.

      The current WordPress mobile plugs are a security risk in my view and I don’t use them as a result.

    3. It seems that WordPress has made some changes. I’ll see after the new years what I can do about setting up a special mobile website. At the moment I can’t do anything (since this needs some testing and other things).

    4. I guess it depends on your browser. Had the same problem with android’s system browser (Chrome Mobile), but you can find a setting ‘manual zoom’ or something like that under settings. Don’t know the exact term though. I use a different language.

  4. I will write about the earthquake in Bárðarbunga volcano later today. At the moment I don’t have the time to do so as I have other obligations today.
