An earthquake with a magnitude of 2.9 has been felt in the east Midlands, according to the British Geological Survey.
The tremor was reported across Leicestershire, Derbyshire and Nottinghamshire.
Julian Bukits, of the BSG, said the earthquake happened at 5.20am and was “average” for the UK.
Leicestershire Police and the county’s fire and rescue services said they had not been called out to any incidents.
The epicentre of the seismic activity was located near Loughborough, Leicestershire, where residents would have felt a bang and a slight vibration.
Mr Bukits said that properties in the area, which has a history of earthquakes, would not have suffered any structural damage.
On October 28, 2001, there was a 4.1 earthquake near Melton Mowbray, Leicestershire, which Mr Bukits described as “big by UK standards”.
Putting today’s quake into perspective, the expert said it was a million times weaker than the 8.9 earthquake which struck off the Japanese coast, causing a devastating tsunami in March 2011.
“Earthquakes generally have to be of 4.5 to 5 magnitude to cause damage,” he added.
Earthquakes in the UK are described as intraplate seismic activity, as they take place far from tectonic plate boundaries.
