Cause of Yorkshire 'earthquake' confirmed by officials after houses 'shake and rumble'

The cause of a possible “earthquake” on the East Yorkshire border on Wednesday was revealed.

North Yorkshire residents described their homes shaking with rumbling noises, fearful that the area was hit by some sort of seismic quake.

At the time, the Volcana Discovery website reported an “unconfirmed” earthquake or “seismic event” in North Yorkshire, 20 miles northeast of York.

It stated: “We received unconfirmed early reports on November 17, 2021 (GMT) at 3:48 pm of ground tremors possibly caused by seismic activity in or near York, England, England, United Kingdom.

“There are still no details about the strength or depth of this possible quake. If this is confirmed, we can expect more accurate data in the next few minutes. “

Meanwhile, a woman posted on Twitter shortly after 4:30 p.m. on Wednesday that she felt her whole house “shake”.

“I felt the whole house shake and rumble about half an hour ago!” She said. “Apparently there was a little earthquake in York an hour away!”

While one man tweeted, “Just had an earthquake near York!”

BGSseismology, which provides “news from the British Geological Survey’s seismology team,” said it was more of a sonic boom than an earthquake.

It said, “We have had some what felt like reports from North Yorkshire, and you can see something on our stations in the area. We believe this is more of a sonic boom from an airplane than an earthquake.”

British Geological Survey supported the theory.

It tweeted: “Data from the BGS seismic networks in the area have been examined and signals consistent with a possible sound origin were recorded between 15.47.42s and 15.49.23s UTC at several stations on the BGS seismic network in North Yorkshire.

“Reports include: ‘house wobbled and conservatory creaked’, ‘a low rumble that ended in a thud’, ‘windows rattled’ and ‘felt the floor shake’.

“The reports received are also consistent with historical observations of previous events of acoustic origin.”

Now the Independent reported A sonic boom from a Swiss fighter jet was confirmed to be the cause.

The Swiss Air Force confirmed that one of their F-18 Hornet aircraft was behind the shock wave, which was felt over a wide area at 3:50 p.m. on Wednesday.

Officials said the aircraft had “routine operational training” and apologized for the inconvenience.

A division of the Swiss Air Force is currently conducting training missions at RAF Leeming in North Yorkshire.

The flight was over the North Sea and the sound could be heard in parts of North Yorkshire and East Cleveland. There were reports from Redcar, Malton, and Whitby.

A spokeswoman told the Independent that sonic booms from aircraft at sea are not normally heard on land, but “climatic and wind conditions” may have been behind the unusual range of the noise.

Sonic booms are the result of shock waves from objects moving through the air faster than the speed of sound.
