A TREMOR which shook parts of Donegal recently is being investigated by scientists who are trying to determine what caused it.
Residents in Ramelton and surrounding areas claim they heard a loud bang which caused the ground to shake and doors to slam and said it felt similar to an earthquake.
The Irish National Seismic Network has confirmed that they examined the data left by the tremor on April 22.

The graph shows a large disruption but it is still not known yet what exactly caused the reading.

Teacher Brendan O’Donoghue, a physics teacher at St Columba’s College in Stranorlar examined the data on a seismometer, a device for measuring such incidents.
Although the centre of the ‘tremor’ is believed to have originated from Ramelton, evidence of it showed up on the school’s seismometer which is located more than 25 miles away.

Mr O’Donoghue stated: “I used some more sophisticated signal filtering software and isolated this signal. Shaking seems to last for about five seconds here in Stranorlar.
“The INSN reports the possible location as Ramelton,” he confirmed.
The exact cause of the tremor has yet to be determined.
