CAN WE GET OVER FEAR OF FRACKING NOW?
On April 1 and May 27 of last year, two tiny tremors were detected by seismographs with magnitudes of 2.3 and 1.5 in England's Blackpool region of Lancashire. They are being blamed on fracking. The same claim is being made in Ohio.
It is now official: drilling for shale gas by fracturing rock with water may rattle the odd teacup. But is highly unlikely to cause damaging earthquakes. That much has been obvious to anybody who has followed the development of the shale gas industry in America over the past ten years. More than 25,000 wells drilled have caused a handful of micro-seismic events that can barely be felt.
To call a two-magnitude tremor an earthquake is a bit like calling a hazelnut lunch. Such tremors happen naturally more than 15 times a year in Blackpool but go unnoticed and they are a common consequence of many other forms of underground work such as coalmining and geothermal drilling.
So can we now get on with fracking and get over fear of it? The economic and environmental benefits are vast.
