Minor earthquake swarm on Reykjanes ridge close to Geirfuglasker island

Yesterday (22-August-2017) a minor earthquake swarm took place not far from Geirfulgasker island on the Reykjanes ridge (no GVP profile). This was a minor earthquake swarm as it was detected by Icelandic Met Office SIL network. There is a chance that more earthquakes happened then where detected. Largest earthquakes in this swarm had the magnitude of 2,4 and other earthquakes that happened where smaller in magnitude.

This earthquake swarm looks like it was mostly due to tectonic movements in this area. It is difficult to know for sure if a magma was at work here due to unclear earthquake signal. It can’t be ruled out. I don’t know when this area last erupted. I think it was sometimes in the time period between 13th and 15th century.

Update 1 on 24-August-2017

According to Rúv News the Geirfluglasker Island collapsed in 1972 but for some reason was still being used by Icelandic Met Office as a point in their system. It has now been updated to Eldeyjarboða area slightly more to the south. I will write about this are in accordance with this new information in the future.

Amazon US/Canada changes

Due to changes in Iceland bank system it is possible that I won’t be able to use Amazon US and Amazon Canada for a while. The change is that my Icelandic bank is going to stop processing checks from 1-January-2018 (along with stop issuing them). I can keep using Amazon US and Amazon Canada advertisements until October (paid by November). I have contacted Amazon US and Canada about this and the word is that Amazon US is working on this. It doesn’t seems to be the case with Amazon Canada but I don’t get much income on it anyway.

What this means at once this change takes place I will go back to getting paid only when people buy something from Amazon UK/DE/ES since with those accounts I use direct bank deposit. This means a drop in income for me since the Amazon CPM advertisement pay considerable more than the advertisement that only pay once people buy something with the Amazon UK/DE/ES banners. I just have to hope that Amazon Europe adds CPM advertisements to Amazon UK/DE/ES so I can switch to it completely. I will start switching advertisement to Amazon UK/DE/ES by November if Amazon US has not resolved the issue by then. It is going to take me few days in November to move everything advertisement from CPM to regular advertisements that only pay when something is bought trough the banners.

Update to Amazon US/Canada payment problem (after 31-December-2017)

Amazon US is looking for a solution to this problem for international associates. Since this issue is not just hitting me. Europe has in general been making checks outdated, this applies not just in Iceland and Denmark. EU even makes a special note on this on their payment information website. What I am going to do is simple. I’ll just keep collecting payments on my Amazon US and Amazon Canada accounts until a new payment system is put in place by Amazon US/Canada. I don’t know how long this is going to take, but it might take a long while until Amazon US/Canada has a new payment system in place.

    And now a solitair star (3.1) as well.

    Katla is waaay too quiet!

  3. Thomas Spencer says:

    Does anyone know what the spikes are in the God lowpass station? Also thoughts on the two small earthquakes at 14km deep at Katla from earlier?

    • The spikes look like earthquakes. As for the deep earthquake, corrected version shows that only one earthquake happened at 14,2 km depth.

      • Thomas Spencer says:

        Ah thanks. I assume the Earthquakes are that small it wont pick up on the Icelandic Met Office site?

      • That can happen at times. But around Katla volcano most earthquakes are detected. If a spike shows up there is a chance it might just be noise on the SIL station. You can always check for it by looking at other nearby SIL stations.

  4. Something is going on at Austmannsbunga SIL station in Katla volcano. This is just this SIL station for now. I don’t know if this is weather, it is not storm winds there at the moment but it is also not quiet weather at Austmannsbunga at the moment.

  5. Thomas Spencer says:

    Spikes are still showing on God and Aus this morning, Is it likely to be Weather? As I would have thought the Aus station would look a bit different in Wind conditions rather than what looks to be a zig zag pattern. With it usually sometimes just shooting up then easing down again

  6. Elmar Þor Benediktsson says:

    Austmannsbunga and around Hekla, not the way it normally calms down after the wind noise.

  7. Saara R says:

    What do you think of these? Katla looks kind of quiet, but…

    • Thomas Spencer says:

      Probably just taking a while for them to go back to normal after the Weather no doubt

  8. Thomas Spencer says:

    Looks like the two Earthquakes at Bárðarbunga been picked up on the SIL stations Aus and God lowpass

    USGS has this :

    130km WNW of Hofn, Iceland USGS

  12. Jan says:

    These were two separate earthquakes EMSC had the 01:45 one as a 4.8.

    Wonder if the 5.6 in the Greenland Sea is connected.
