Residents in North Yorkshire have reported homes shaking, windows rattling and feeling the ground tremble, following what has been described by experts as a “sonic event”.
Initially, people reported a suspected earthquake in the area at around 3.50pm, according to the British Geological Survey (BGS).
Some social media users said they felt a quake in the town of Malton.
However, following analysis, seismologists have established it was the result of a sound as opposed to movements in the ground.
One resident, Dr Amy-Jane Beer, tweeted: “Felt in the air and all through our bodies near Castle Howard.

“The house shook, I could see the windows vibrating… It sounded like something really heavy falling over in the house next door,” he said.
“I suppose it (could) have been a sonic boom,” the 48-year-old added.
A sonic boom is a thunder-like noise a person on the ground hears when an aircraft or other type of aerospace vehicle flies overhead faster than the speed of sound, or “supersonic,” according to NASA.
