My comment: I do not remember news on earthquakes in the UK and reading this I was a bit surprised, I surfed more and I read on the BBC website that there have been more earthquakes earlier this year in North Yorkshire in January 2011 with a magnitude of 5.5 and in June 2011 in Devon with a magnitude of 2.7.
