A CONTROVERSIAL “fracking” technique to extract gas was the “highly probable” cause of earth tremors which hit Lancashire’s Fylde coast earlier this year, a report has concluded today.
One tremor of magnitude 2.3 on the Richter scale hit the area on April 1. This was followed by a second of magnitude 1.4 on May 27, which prompted locals to blame fracking used by the oil and gas firm Cuadrilla.
Fracking involves extracting gas reserves from underground through the hydraulic fracturing of shale rock using high pressure liquid. Green groups claim the process damages the environment.
