Less than two weeks after an energy company won a court battle over opponents who feared hydraulic fracturing would cause seismic tremors in northwest England, the drilling work appears to be doing just that.

On Tuesday and Wednesday, monitors in Lancashire, where the fracking operation is underway along Preston New Road, recorded tremors that registered just below the threshold for shutting down drilling. Weaker tremors were recorded last week.

Jacqui Reid, a spokeswoman for Cuadrilla Resources, the company operating the site, said that Cuadrilla had halted the fracking after the tremor on Tuesday, but that it would proceed with the work, although cautiously. She said Cuadrilla, whose fracking had been moving much more slowly than would be common in the United States, hoped to accelerate the pace next week.

“Regulators have been advised and we anticipate we will continue work at Preston New Road tomorrow as planned,” the company said in a statement on Wednesday.
