Controversial ‘fracking’ technique to extract gas from the ground was the ‘highly probable’ cause of earth tremors, report finds
The two tremors – magnitude 2.3 and 1.5 – which were felt by people just outside Blackpool, but did not cause any known damage, were reported in April and May. Since the second event, Cuadrilla Resources has stopped “fracking” operations – where water and chemicals are injected into rocks at high pressure to extract gas from the cracks.
The news came as protesters against the controversial new energy source halted work at a Cuadrilla gas exploration rig at Banks, near Southport, Merseyside. Four members of the environmental campaign group Frack Off unfurled banners after climbing climbing the rig at around 5.30am on Wednesday. Others remained on the ground.
In a separate protest in London, around 50 anti-fracking activists gathered from around 3pm outside the Copthorne Tara hotel in Kensington in an attempt to disrupt an industry conference organised by by SMI international. Two dozen police kept demonstrators away from the conference on the hotel’s first floor which was attended by delegates paying £1,500 per head.
The report, by a team of European seismic experts not usually employed by the company, concluded it was “highly probable” that the two main tremors and a series of aftershocks were caused by Cuadrilla’s operations at the Preese Hall-1 Well in Lancashire.
