Small earthquakes detected near Lancashire fracking zone

The British Geological Survey (BGS) has detected tremors in the vicinity of a controversial fracking operation in Lancashire.Energy firm Cuadrilla started hydraulic fracturing at the site in Little Plumpton, near Blackpool, earlier this week after an unsuccessful High Court appeal to block it.In a statement, the BSG said that the seismic activity recorded on Friday evening was "not unexpected", as hydraulic fracturing is "generally accompanied by microseismicity".
