UK Quakes Could Be Linked to Shale Fracturing, Expert Says

摘要

Adding more heat to the debate over use of hydraulic fracturing to extract shale oil or gas, pioneering UK unconventional explorer Cuadrilla Resources has postponed a fracking program near Blackpool in northern England following the second minor earthquake close to its drilling site in as many months. The first quake, measuring 2.3 on the Richter scale, occurred on Apr. 1, and the second, measuring 1.5, was recorded on May 27, 2 kilometers from Cuadrilla's Preese Hall site in Lancashire.
