A minor earthquake measuring 2.2 on the Richter scale struck Grimsby and surrounding areas Tuesday evening, prompting residents to report feeling shaking and rumbling.
The tremor originated approximately 5 kilometers beneath the Earth's surface and was felt at 7:47 p.m. Residents in Grimsby and nearby Cleethorpes described hearing a sudden bang and experiencing shaking within their homes. Some reported the sensation of a quick shake, initially believing something heavy had fallen, while others heard a deep rumble they mistook for thunder. Online posts indicated that some residents felt their homes "shake and tremble."
The British Geological Survey recorded the event, classifying it as minor, which means it was perceptible only to individuals close to the epicenter. Such minor seismic events are not uncommon in Britain, with up to 300 recorded annually.
The United Kingdom is not situated in a seismically active zone. Earthquakes affecting Britain typically measure between 2 and 3 on the Richter scale. A more significant event, the Dogger Bank earthquake in 1931, registered 6.1 and struck the North Sea off England's northeast coast, with its effects felt across Britain, France, and Belgium.
Grimsby has experienced seismic activity in the past; a 3.9 magnitude earthquake was centered on the town in 2018 and was felt up to 60 miles away.
