Early this morning (7-September-2016) an earthquake with the magnitude of 3,5 took place in Katla volcano. There was little earthquake activity before the main earthquake and after it, since this morning activity has remained low.
This earthquake activity is in the same area of the magnitude 4,9 earthquake two weeks ago. No harmonic tremor has been detected following this earthquake. I don’t know if anything more is going to happen. All that can be done is to wait and see what happens next.
