A small earthquake swarm started today (30-June-2019) east of Grímsey island. Largest earthquake in this swarm had a magnitude of 3,6. There are no news that it had been felt.
This is one of several earthquake swarms in this area of Tjörnes Fracture Zone this year. More activity can be expected in next few months. This earthquake swarm activity appears to be only tectonic in nature.
