During the night of 23-July-2020 at 05:36 UTC a magnitude Mw3,3 earthquake took place in Katla volcano. There was no change in harmonic tremor following this earthquake and that means that magma stayed were it is in Katla volcano. In the hours since this earthquake took place there has not been any increase in earthquake activity or harmonic tremor change in Katla volcano.

Earlier earthquakes had a magnitude of Mw2,4 and Mw2,7. All other earthquakes were smaller in magnitude. I don’t expect anything more to happen now and Katla volcano remains quiet.
