The magnitude 3.5 ML Oakham earthquake on the 18 February 2014 occurred at 06:50 UTC (07:50 BST), with an epicentre approximately 7 km NNW of Oakham, Rutland, and 11 km SSE of Melton Mowbray, Leicestershire, almost 24 hours after a magnitude of 3.2 ML earthquake had occurred in the same vicinity. This was the largest earthquake to have occurred in the area since the magnitude 4.1 ML Melton Mowbray earthquake of 28 October 2001. Earthquakes in the magnitude range of 3.0-3.9 ML can be expected to occur around three times per year on the mainland UK. Analysis of the 760 felt reports received from members of the public via an automatic online questionnaire survey shows that most of them came from within a 30 km radius of the epicentre, particularly from Oakham, Melton Mowbray, Leicester, Stamford, Grantham and Corby and their surrounding hamlets. Up to around 40 km away, a number of felt reports were received from the Loughborough, Kettering, Wellingborough and Peterborough areas. The furthest felt reports were received from near Tamworth and Burton-upon-Trent, approximately 60 km to the west of the epicentre, and Cambridge, approximately 85 km to the southeast of the epicentre (see map).
Most people described the shaking strength of the earthquake to be either weak or moderate, with mainly a trembling effect, whilst others described the effect as like an impact or jerky. About half of the reports described the sound strength as being moderate. More than half of the reports stated that windows rattled and one sixth mentioned crockery rattling and furniture shaking. One sixth of people also reported that they had been alarmed or frightened. Reports described “glasses in sideboard rattled”, “bedside chest of drawers both sides of the bed creaked as if being moved.”, “Metal patio chairs moved away from table”, “Deep rumblings with a very loud bang then more rumbling”, “water in dog bowl rippled”, “outside wall I was leaning on trembled and bed shook slightly” and “felt like a hard thump in the back of the chair I was sitting in”.
