A MINI earthquake has been recorded off the Cork coast – for the first time since records began.

What has been described as definite "seismic activity'' has been noted in the region.

The Irish National Seismic Network (INSN) confirmed the earthquake occurred at 7.57am yesterday morning in the Celtic Sea.

It is the first known event of its type since monitoring began in 1978.

The quake was probably caused by stresses built up from the weight of glaciers covering the landmass during the Ice Age, according to the INSN.

It took place about 18km south of Ballymacshoneen on the Seven Heads Peninsula in west Cork.

And the INSN's seismometers picked up aftershocks in areas such as Courtmacsherry and Timoleague in the county – over 25km away from the epicentre.

No injuries have been reported.

INSN director Tom Blake said it was unusual that the earthquake – measuring 2.6 on the Richter scale – happened in the Celtic Sea.

"This occurred in a region that has not previously shown any seismic activity since we started recording activity 35 years ago," he said.
