Earthquake swarm in Katla volcano yesterday (13-July-2017)

Yesterday (13-July-2017) an earthquake swarm took place in Katla volcano. As earthquake swarms goes this one was minor one and largest magnitude was only 2,7 all other earthquakes where smaller in magnitude.

One magnitude 2,5 earthquake happened today (14-July-2017) at 16:29 UTC. Since then everything has been quiet in Katla volcano. This current repeating earthquake pattern is starting to look like long term signs that Katla volcano is going to erupt soon. How long is not known, but it is my best guess that an eruption might happen either this fall or next year (2018). It is not possible to get any better idea how long it might be until an eruption happens in Katla volcano.

Update 1 (July-15 earthquake activity)

At 19:12 UTC on 15-July-2017 a magnitude 3,3 earthquake took place in Katla volcano. Earthquakes that followed where smaller in magnitude, with only one having magnitude 2,8 today (16-July-2017) at 10:51 UTC. I was unable to record it due to high noise level on my geophone.

Earthquake activity has quieted down again for now in Katla volcano.

Donations

Please remember to support my work with donations. At the moment I’m completely broke and this is going to be a problem for me until the end of this year (2017). I hope this going to be a less of a problem first part of 2018 and I hope to have no problem at all in the second half of 2018. I also need to get paid for my work like anyone else and on the internet that is only done by donations and advertising income. Thanks for the support. 🙂

  3. I’ll post an update about this magnitude 3,3 earthquake here later today.

    Thanks for updates, Jon!

    Just turned on my computer, haven’t even looked at the other stations nearby. Is it windy, or something going on?

    Have you seen Austmannsbunga tremor? Only one plotter with
    Wind noise hmmmmm

    • Z says:

      I got a bit excited too :). Austmannsbunga is located at a much higher altitude than the other stations in that area, that is probably why.

    Got a reply from the met office, there is really bad whether up there 🙂

    Sad to say, the map site volcanodiscovery.com seems to be no more. Does anyone have a suggestion for an alternate site to view Iceland earthquakes on a map?

  8. William Gunning says:

    Hi Mudpot goto Icelandic met office and hit earthquakes

  9. Z says:

    Looks like one big EQ, or a series of smaller ones, occcured a moment ago. In Katla caldera. Most probably a green star. Drumplot shows a lot of small ‘popping’ over the last hours.

      Looking at the table on en.vedur.is for Myrdalsjokull area showed much of that activity at 0.1 km depth including the 3.1 quake. Interesting times.
