Ongoing earthquake activity north-east of Flatey in Skjálfanda fjord (north-east Iceland)

Earthquake activity that started in March 2017 in TFZ (Tjörnes Fracture Zone) is ongoing. I don’t know yet how many earthquakes have happened so far, but at last check Icelandic Met Office reported that the mark was at 800 and that was more then a month ago. The fluid that is pressuring up at this location between fault lines is most likely a magma in my view. If that results in a eruption is harder to say, at the moment the magma seems to be stuck at 10 km depth (in or around that depth).

The earthquake activity at this location continues with little signs of stopping. What is also interesting is the fact the magma doesn’t seems to be making any progress up the crust at the moment. With fault line already in place the path to the surface is almost direct in this area if nothing is preventing the magma from moving upwards (impossible to know). At the moment this earthquake activity is limited to minor earthquakes and this magma seems to be lacking pressure to reach the surface at the moment. At this location there are no known volcanoes.
