A magnitude 3,5 earthquake happened in Öræfajökull volcano at 16:57 UTC. This is a automatic magnitude and is going to be corrected later. A swarm of earthquakes seems to have started in Öræfajökull volcano.
The harmonic tremor images have not yet updated so I don’t know at the moment if any harmonic tremor has started following this earthquake swarm.
