TREMORS felt across Northumberland have been confirmed as a sonic event.
The British Geological Survey (BGS) has said that shakes and tremors felt across the county this afternoon were not related to an earthquake but to a sonic event which took place at around 3.15pm.
A stated on the BGS website says reports such as ‘I heard it as a low frequency rumble’, ‘whole house shook’ and ‘heard a very loud boom’.
They said RAF Kinloss was contacted and has advised that there were two military jets on exercise in the area at the time.
It added: “Data from the BGS seismic networks in the region were examined and a signal consistent with a possible sonic origin was recorded at 3.13pm.
“The reports received are also consistent with historical observations received for previous events with a sonic origin.”
