A second earthquake of magnitude 2.4 was also recorded in Donegal on April 7, around the Killybegs area.
Speaking on RTÉ’s Morning Ireland, Brendan O’Donoghue explained that Donegal is situated along the boundary of an ancient collision between two ancient continents.
He said the “cracks would still be in the Earth’s crust” and these events are the releases of small amounts of energy….
Or ‘they’ are dynamiting ‘things’ underground.
We may never know.
