Minor earthquake swarm in Katla volcano

Send to Kindle

This Sunday is not quiet when it comes to earthquake activity in Iceland. Earlier today a small earthquake swarm started in Katla volcano. The largest earthquake in this swarm had the magnitude 2.3 according to the automatic SIL system. The largest earthquake did appear clearly on Skeiðflöt and Heklubyggð geophone stations. But Skeiðflöt geophone station is closest to the area where this earthquake swarm was taking place.

It is impossible to know what happens next in Katla volcano. But it is monitored heavily, so if anything happens. It is going to show up almost in real time on the internet.

GPS monitoring of Ice cauldron on Mýrdalsjökull glacier

In the news on Rúv yesterday (07.07.2012) they did tell about real time GPS monitoring of ice cauldron in Mýrdalsjökull glacier. But it is hoped that with this real time GPS monitoring they can give out warning sooner when a ice cauldron empties it self of the water it holds.

The news about this can be found here on Rúv News in Icelandic.

    Some ideas about the earthquakes around Skjaldbreið and Langjökull:
    Wednesday 11.07.2012 08:58:18 64.643 -20.551 4.6 km 3.0 99.0 16.1 km
    Are they tectonic?

    • Yes. I believe that they are tectonic in nature. Same goes for the earthquakes in SISZ. But there seems to be some type of tension going on in the area. I am not sure what it means.
