THE IRISH SEA experienced an earthquake last night – the second in a month.

Data from the British Geological Survey shows the quake, with a magnitude of 2.8, struck just before 10:30pm last night.

The epicentre of the quake was just off the Lleyn Peninsula, about 2 kilometres from the Welsh coast, and around 50 kilometres from Wicklow.

The BGS said it was located only around 500 metres south of the quake on May 29, which reached a magnitude of 3.8 and which was felt across south-east Ireland.

Dr Yochai Ben-Horin of the Dublin Institute for Advanced Studies, which operates the Irish National Seismic Network, said there had been no reports of the earthquake being felt in Ireland, but that the quake was quickly recorded by Irish seismologists.

Ben-Horin said there had been an increase in seismic activity in recent months – and that the quake could be the latest in a series of activity that began in February when there was a 2.3-magnitude struck.

“It is unclear whether stronger earthquakes are likely in the coming weeks but aftershocks can be expected in the hours and days ahead, although many will be too weak to be felt,” he said.
