LONDON (Reuters) - An earthquake with a magnitude of 5.2 shook parts of Britain on Wednesday but officials said there were no reports of anyone being killed or serious damage.
"(The quake) was really bad. I was fast asleep and woke up and the room was shaking," Jemma Harrison, who lives in Manchester, told the BBC.
Soon after the quake occurred the U.S. Geological Survey (USGS) estimated the magnitude at 4.7, but the British Geological Survey later raised the figure to 5.3 before settling on 5.2.
The USGS said on its Web site the quake's epicentre was 127 miles north of London and 50 miles east of Sheffield.
"We have no reports of injuries (in London)," said a police spokesman in the capital.
Police in Lincolnshire said some people had reported minor damage to their homes.
The quake was the largest to hit Britain since one with a magnitude of 5.4 in 1984.
"This is a significant earthquake for the UK and will have been widely felt across England and Wales," said seismologist Brian Baptie of the British Geological Survey.

Although they lasted only three years, they have recorded one album and four singles, which forever changed the world music scene. At the Exit, they will perform in their original line-up: Johnny Rotten, vocals, Steve Jones, guitar, Glen Matlock, bass guitar, and Paul Cook, drums.
Best of all, after 30 years, the fans at Exit will get the opportunity to hear the new songs of this legendary British band. According to egigs.co.uk, Paul Cook confirmed this possibility, but he also expressed his doubt regarding the release of a new album, since John and Steve live in USA, whereas Glen and he are in the UK.
"We might not pull together an album but hopefully there will be some new stuff in time for the summer," said Paul Cook.
The Sex Pistols are not the first punk band, but they certainly are the band which participated in the making of the massive independent underground scene in England and America. The release of the album "Never Mind the Bollocks, Here's the Sex Pistols" is considered as one of the most important events in the history of the popular music, and the album is regularly cited on lists of the greatest albums ever. In 1987, Rolling Stone Magazine listed this album at No.2 on the "Top 100 Albums of the Last 20 Years"; while in 2004, it was listed at No. 58 on their list of the "100 Greatest Artists of All Time". In Q Magazine, the only Pistols' album ranked No. 27 on their list of the "100 Greatest Albums Ever".

From there it’s onto the song that launched a thousand alt. bands, ‘Mayoniase’. Over 15 years since its inception, it still sounds seminal enough to launch another thousand more bands. Now moving into this mid-section of the set list and being bombarded with hit after hit, it’s almost a return to the glory days. Juxtaposing the energetic new material such as ‘Come on (Let’s Go)’ with the dainty ‘Perfect’ illustrates the diversity of this band when in its full swing. And followed by the shining jewels ‘Today’, ‘Stand Inside Your Love’ and ‘Ava Adore’, it’s a feeling of sheer elation to be a witness to this rock spectacular. The usually dour Corgan even cracks jokes before ‘Drown’, then hits the audience with a surreal yet enticing rendition of
