Earthquake measuring 4.0 magnitude recorded off West coast of Ireland

An earthquake measuring 4.0 magnitude has struck off the west coast of Ireland.

It happened 60 km off the County Mayo coast at around 9 o clock this morning.

According to the British Geological Survey, which monitors earthquake activity, it was strong enough to be felt in counties Mayo, Galway and Sligo.

The BGS said it had not recorded an earthquake of that magnitude in that area previously.

The light tremor was measured at a depth of 15 km.

Similar sized earthquakes have been registered across the British Isles, normally every three to four years.

Micro tremors were felt in parts of north Donegal in January and March this year near Buncrana.
