controversial "fracturing" to extract gas from the earth was "very likely" the cause of earthquakes, according to a report

Two tremors of the earthquake in north-west England earlier this year were probably caused by gas extraction operations near a responsible company report concluded.

The two earthquakes - magnitude 2.3 and 1.5 - that people feel in the outskirts of Blackpool, but caused no known damage was reported in April and May Since the second event, crew resource stopped "frac" operations - where water and chemicals are injected into the rocks at high pressure to extract the gas from fissures

The news came as protesters against the new source of energy and controversial work team stopped at a gas drilling exploration in the banks, near Southport, Merseyside. Four members of the campaign banners environmental group Frack fly after climbing the platform around 5:30 on Wednesday. Others remained on the ground.

a separate event in London, about 50 anti-fracture militants gathered around outside the Copthorne Tara in Kensington 3:00 p.m., in an attempt to disrupt an industry conference organized by the International SMI. Two dozen police kept protesters away from the conference on the first floor of the hotel, attended by delegates to pay £ 1,500 each.

The report, conducted by a team of European experts in seismic is not usually used by the company concluded that it was "highly probable" that the two major earthquakes and a series of aftershocks were caused by the operations of the crew in the Hall of Prees -1 Well, in Lancashire.

He said, however, that the cause was an "extremely rare" combination of factors, including pre-existing fault in the rocks, and that it was "unlikely" to occur elsewhere in the Bowland Basin, where the crew hopes to operate at 200 trillion cubic feet of shale gas.

"If these factors combine to return in the future, the limits of the local geology and seismic events of magnitude of about three as the" worst case "scenario," said a statement from the the company.

Opinion is divided on the gas industry fracturing huge and growing in North America. Opponents say the industry pollutes groundwater pollution and adds to greenhouse gas emissions from fossil fuels, which leads to ban the practice in some places, including France. Supporters say fracturing is safe and provides a valuable energy in a time of conventional gas and oil supplies are expected to be short and prices high.

fracturing A report by MPs published in May, said shale gas in the UK could improve the energy efficiency of the country "self" and reduce the use of highly polluting power plants to coal. But he said it was "unlikely" that the industry could improve energy security and reduce prices, and warned it could hurt government efforts to stimulate the production of renewable energy. "Overall," the committee recommended fracturing should be allowed to proceed provided it is well regulated and closely monitored.
