Moderate tremors measuring 1.5 and 1.7 on the Richter scale stuck Donegal on Tuesday night and Wednesday morning of this week.
The first happened around 8.50pm on Tuesday night, with the epicentre located in an area called Clonmore, south of Buncrana stretching between the south of the Inishowen peninsula and Letterkenny. According to witnesses it sounded like a low flying jet following by vibrations. The second occurred at approximately 7.50am on Wednesday morning and appears to have affected the same areas.

According to Dr Blake all the children at St Egney's N.S., Desertegney, Buncrana felt the tremor. They are actually one of the schools that hosts seismometer for the DIAS as part of the Seismology in Schools Programme.

"These are normal events that can happen from time to time but not suspicious or dangerous. Not everyone felt this week's tremors but if they did the Institute would be indebted if they would contact us via our website www.dias.ie and fill in our questionnaire about the incident. It's very important that we get this information to know the full extent where it was felt in Donegal to help us with our studies."
He added there were similar tremors in the 1980s and 1990s.
