A magnitude 3.8 earthquake has struck the North Sea off the coast of North Yorkshire, the British Geological Survey (BGS) said.
The quake hit 150 miles east of the seaside town of Scarborough at 6:52pm.
Staff at two local pubs said they were not aware of the quake and had not felt any movement.
BGS originally reported a tremor of magnitude 3.9 from its devices in Glasidale, around 10 miles east of Whitby.
The quake's centre was 18km deep and was located around 50km from the largest ever earthquake to hit the UK of magnitude 6.1 in 1931.
Hundreds of earthquakes, almost all too faint to be felt by humans, are detected in the British Isles each year by the BGS.
In 2011, a 3.6-magnitude quake struck North Yorkshire around five miles north west of Ripon.
Tremors were felt in the towns of Bingley and Skipton, near Leeds, where people reported doors, windows and heavy furniture rattling, reported the BBC.
