This is not going to surprise anyone how read this blog on regular basis. But earthquake activity and volcano activity in Iceland is minimal those past days. As it has now been for past several weeks. This has sadly lead to less blog post then I like. But I have also been busy. So it has helped in that sense for me. At current rate, the year 2012 is so far the most quiet year that I remember in an long time. I have been monitoring earthquake activity in Iceland more or less since the year 1996.
Current earthquake activity in Iceland on 29. August 2012. As can be seen. Activity is rather slow today. Copyright of this image belongs to Icelandic Meteorological Office.
While it is quiet in Iceland. I am going to work on other articles about other interesting features in Icelandic geology. They won’t be long. But short and as informal as I can make them. This quiet time might last a bit longer then it already has. I would not expect anything else.
A M3.9 close to Bláfjallaskála after you post that…
A massive M6.6 near Jan Mayen… Shows up nicely on my geophones in Oslo, and the seismometer went off scale…
I did check my data here in Bov, Denmark. I did record the Jan Mayen earthquake on my geophone. I can see the P-wave clearly. But not other waves due to background noise that I always have.
It’s hard to see the S wave clearly on my geophones as well. Only when I use a low pass filter at 1 Hz or lower I can see it. I have some noise too, since this happened at daytime, and it was slightly windy today also.
On the seismometer (17s period) the S wave goes off the chart. http://voksenlia.net/nytt/2012/jordskjelv-20120830.jpg
My distance is 1595 km.
You can now see the images on how this earthquake did appear on my geophones in Iceland and in Denmark.
Now there is activity with tremors. Due to the M6.6 at Jan Mayen..or did this cause changes?
I don’t see any tremor as of yet. Just normal background activity.

New information on Skaftár glacier flood has been released. So I am going to write three blog posts today. If nothing more happens today.
That’s what happens when you talk about quiet times 🙂
