In some parts of Iceland, mostly in the high areas of Iceland the ground is freezing over this time of the year. This is creating a lot of glacier-quakes and ice-quakes in Iceland. On Icelandic Meteorological Office earthquake maps this appears as earthquakes with extremely poor quality. Many of the earthquakes in and around Mýrdalsjökull glacier and Eyjafjallajökull volcano are glacier-quakes and ice-quakes.
So while it might appear as a lot of earthquake activity is taking place. That might not be true earthquakes. In this case, it is best to wait for reviewed data on this activity. To see what is real earthquake activity and what is not real earthquake activity.
Thanks Jón for the reminder
