Fracking Tremors

Study locates 68 minor earthquakes in Barnett Shale area of Central Texas, 23 of them close to injection wells where waste water from energy extraction was pumped deep underground for disposal. Last year in Britain, the government temporarily halted fracking in Blackpool after tremors were recorded at that site.
