Felt Nottinghamshire, Derbyshire and Leicestershire. The majority of the reports (around 370 as at 21 January 2013) that we have received, from members of the public, have been within a 25km radius of the epicentre.

Updated 22 January 2013 12:00 UTC

The earthquake of the 18 January occurred at 05:20 UTC, with an epicentre approximately 4 km NNW of Loughborough, Leicestershire. The instrumental magnitude was determined at 2.9 ML, and the estimated area over which an earthquake of this magnitude and depth (13 km) would be felt was calculated to be a distance of up to 60 km from the epicentre. Analysis of the results from an automatic online questionnaire survey agreed with this. Some 240 felt reports were received out of a total of 370 completed questionnaires. Of those 240 felt reports, the majority came from an area within a 25 km radius of the epicentre, namely from the towns of Loughborough, Derby, Leicester and Nottingham. Around 20 credible reports were received from beyond this area with the furthest afield being from near Buxton (60 km to the NNW), near Warwick (57 km to the SE) and Corby (50 km to the SSE). The felt area was elongated in an NNW-SSE direction, the long axis being about 120 km and the short axis around 65 km (see map).

Most people described being woken from their sleep, the shaking strength of the earthquake to be weak-moderate and the sound strength to be faint-moderate. Reports described “bed rattled and the books all fell off the shelf”, “first a rumble, then felt the wave move from front to back of house”, “like a slow distant grumble and then the force seemed to come up stronger, my bed was shaking, the noise was louder and then faded away”, “sounded like an impact blast from an explosion because it made the window vibrate”,  “sounded like a train or lorry crashing then a shake of house” and “sounded like a large lorry passing along a road some distance away”.
