Earthquake with magnitude of 3,4 in Bárðarbunga volcano

After a long period of quiet an earthquake has happened in Bárðarbunga volcano. This earthquake had a magnitude of 3,4 and was in the usual place of central caldera of Bárðarbunga volcano. This earthquake had a smaller earthquake swarm activity happen few hours before it happened.

It is not possible to know if this means there is going to be any more earthquake activity in Bárðarbunga volcano. Normally since everything started to quiet down, just one earthquake happens that is over magnitude 3,0 and then everything goes quiet again for several weeks to months. I do suspect that is going to be the pattern this time.

Due to how tired I am since I am working full workday (08:00 – 16:00) now my English grammar is all over the place in this article.

  1. Many thanks for your article, Jón, it is greatly appreciated. I am wondering if an EQ in the centre of a caldera has any special significance within the overall pattern?

  2. Jón, I misread what you said, no need for a reply, I now realise the EQ is in the usual area.

  3. Hey Jon
    We see many swarms since 2014 in an area directly east of Bardarbunga. As far as I kbow there arent any known volcanoes around there (to the north of Grimsvotn).
    Any idea what could be happening there? Just tectonic settling from the recharge of Bardarbunga and Grimsvotn? Or just a tectonic process as it is above the MAR? Or soemthing else?
