Since the weekend there has been a earthquake swarm ongoing in Breinnisteinsfjöll volcano (Wikipedia link). This earthquake swarm has not been strong in magnitude of the earthquakes happening, with largest magnitude just at 2,8 and all other earthquakes being smaller in magnitude. Close to 130 earthquakes have happened so far.
The signal from this earthquake swarm shows that some of the earthquakes happening are hybrid earthquakes. That means magma is creating some of them. While tectonic process is creating others. Last eruption in this volcano was in the year 1341 and I don’t have a lot of information about it. I don’t know if this is only magma that erupts or a mix eruption (magma and ash cloud). The earthquake swam is highly localized but has moved slightly to the south from the area where it started during the weekend. The earthquake swarm appears to be ongoing as is, there are however quiet period in it and currently that is what is happening.
Please remember to support with donations. I spend a lot of time working on this website when something is happening in Iceland. Thanks for the support. 🙂
