A sonic boom has been heard in North Yorkshire, causing windows to shake and leaving locals scared an earthquake has struck the area.
Residents reported feeling an "earthquake" at around 4pm today which saw kids freeze in fear and dogs hiding under the bed.
People as far away as Halifax and parts of West Yorkshire said the ground was "trembling" after the event.
The British Geological Survey (BGS) initially received reports of a suspected earthquake at around 3.50pm on Tuesday.
But following analysis of its network of seismic measuring equipment, seismologists determined it to have been the result of a sound as opposed to movements in the ground.

The origin of the phenomenon is currently unknown and BGS said it was unable to comment on sonic events.
People in Brotton, Redcar and Cleveland, Pickering and Skelton have all tweeted to say they have heard and felt it.
A sonic boom is an explosive noise caused by the shock wave from an object travelling faster than the speed of sound - 767 mph (1234 km/h).
Locals have reported the event, saying it felt similar to a small earthquake.
Peter Williams tweeted: "Never felt an earthquake before, but a minor one rattled the doors this afternoon while I was working. Must admit I thought it was a lorry or the dog trying to get in though until I saw it on the local news. Not exactly a disaster film."
Another person added: "My building shook for approximately 6 seconds accompanied by a loud rumbling. At first I thought train derailment or landslide. Nothing like sonic booms previously heard. Bizarre then."
@AP_82 tweeted saying: “Earthquake felt in Pickering, Yorkshire.”
@OliverFindlay said: “That was either an #earthquake or an underground explosion from the Boulby mine just then. Our house shook! On the North Yorkshire Coast.”
