Earthquake strikes off Co Mayo coastline - Map showing locations from where people reported that the felt the affects of this morning’s earthquake, which struck 60km off the Co Mayo coastline.
The earthquake, which registered a magnitude of four on the Richter scale, was recorded as 60km west of Belmullet, Co Mayo, at a depth of 3km, at 8.58am. It was the largest local seismic event ever recorded, according to Tom Blake of the Irish National Seismic Network (INSN) and the Dublin Institute of Advanced Studies.
It was also the second-largest local earthquake on record in either Britain or Ireland, he said - the first being of 5.4 magnitude on July 19th, 1984, off the west coast of Wales and felt in Waterford and Wicklow.
A 2.7 magnitude tremor was recorded in Lisdoonvarna, Co Clare, in May 2010.
The Irish Coast Guard recorded instances of structural damage to houses in Erris, Co Mayo, yesterday and the British Geological Survey said the impact was felt in Galway, Mayo and Sligo.
The Geological Survey of Ireland said earthquakes of this magnitude at this depth were "not very unusual although not common".
However, Mr Blake said that while the earthquake was classified as "moderate", it was "significant" in that it challenged existing information about seismic activity off the west coast.
Comment: One has to wonder if the oil and gas drilling in this exact area of Italy, the gas drilling having begun late last year, has anything to do with these earthquakes...

Then there were the recent strong earthquakes in Bulgaria and Norway. Things be rockin' and rollin'!
5.6 earthquake which jolted Bulgaria was strongest since 1858, and the aftershocks continue
