The magnitude 3.2 ML Oakham earthquake on the 17 February 2014 occurred at 06:07 UTC (07:07 BST), with an epicentre approximately 7 km NNW of Oakham, Rutland, and 11 km SSE of Melton Mowbray, Leicestershire.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 580 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 report was received from near Mansfield, approximately 60 km to the northwest (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. Just over a half of the reports stated that windows rattled and a few mentioned crockery rattling and furniture shaking. One quarter of people said they had been alarmed or frightened. Reports described “a very loud rumbling like a heavy truck that got louder then disappeared slowly”, “radiators rattled quite violently”, “it was sudden and sharp rumbling and shaking, which then tailed off in a long rumble”, “I heard a very loud rumbling noise then felt a definite vibrating rippling movement move from the back of the room to the front”, “very quick loud bang with a quick rumble after”, “I was in bed and the bed was shaking, audible rumbling noise” and “I thought someone in neighbourhood was using a massive drill in the house”.
