Minor earthquake swarm in Skjaldbreið

During the night a small earthquake swarm started in Skjaldbreið south of Langjökull glacier (might be part of Presthnjúkar volcano). This earthquake swarm is minor. With largest earthquake only being magnitude 1.9. While this is an minor earthquake swarm there seems to be more activity taking place then appears on reviewed and automatic SIL map. The reason for that is the earthquakes in questions are small to be located by three or more SIL stations in the area. While this unseen earthquake activity does not appear on Icelandic Meteorological Office maps it can be seen on the SIL station closest to the earthquake locations.

Earthquake activity is common in this area. Since it is on the tectonic plate boundaries in Iceland. It is difficult to know how this earthquake swarm is going to behave in the next few hours. But so far it has stopped for few hours before continuing again.
