The earthquake of the 28 January 2015 occurred at 22:25 UTC with an epicentre approximately 7 km north of Oakham, Rutland.
The instrumental magnitude was determined at 3.8 and was in close proximity to two similarly sized events, with magnitudes of 3.2 and 3.5 ML that occurred on 17 and 18 April 2014 respectively.
The estimated area over which an earthquake with a magnitude of 3.8, and depth of 8 km, would be felt was calculated to be a distance of up to approximately 150 km from the epicentre (at intensity 2 EMS).
Analysis of the results from an automatic online questionnaire survey agrees with this.
Just over 2000 felt reports have been received, so far. Of these, almost all of them came from within a 50 km radius of the epicentre, from Lincoln in the north to Kettering in the south, and from Uttoxeter in the west to Wisbech in the east. There were a fair number of reports from locations much further afield, the extremes being from the likes of Ripon in the north (150 km from the epicentre), Luton in the south (125 km from the epicentre), Telford to the east (125 km from the epicentre), and Aylsham to the west (125 km from the epicentre)
Half of the reports described the shaking strength of the earthquake as being moderate, with more than half describing the shake itself as having a trembling effect, whilst others described it as either like an impact, or jerky. The sound strength was described as moderate to loud in the majority of the reports. Over 250 people reported having been awoken by the event and 700 said they were frightened. Almost half of the reports stated that windows or crockery rattled and a few people reported objects, plants or books moving. Reports described how “there was a deep rumble a slight shake and a moderate jolt”, “sound was quite loud; rumbling continued for perhaps 15 seconds before fading away”, “sofas juddered, noise was like spin cycle on washing machine “, “I could see rings in my glass of wine! A bit like in Jurassic Park when the T Rex chases the car!” and “very loud rumbling noise - sounded like a large piece of concrete rolling around”.
