An earthquake measuring 2.8 on the Richter scale was felt off the east coast early this morning.
The tremor occurred 30km due east of Bray Head, Co Wicklow at an estimated depth of 9km, according to the School of Cosmic Physics at the Dublin Institute for Advanced Studies.
Senior Professor of Geophisics Alan Jones said the quake occurred at 3.30am.
"I live in Greystones, it didn't wake me up but we had reports from people in being woken up," he said. He said more information would be available this weekend.
He also said there was a dire need for Ireland to have it's own seismic network, as we currently rely on information from the British Geological Survey.
"We don't want to scare people, but there is not enough information to satisfy the Irish public", Prof Jones added.
No structural damage has been reported following this morning's quake. In 1984 a quake measuring 5.4 on the Richter scale was felt along the east coast causing some minor structural damage.
