Fracking company Cuadrilla has requested an urgent review of existing earthquake safety levels, hoping that the permission to generate larger tremors will allow them to extract greater quantities of shale gas from Lancashire. Currently they must suspend drilling when quakes measuring over 0.5 magnitude are detected. Although numerous legal challenges and protests were not enough to prevent the company from beginning exploratory drilling at Preston last year, it is now the government’s ‘traffic light system’ for seismic activity which the industry appears to consider the greatest threat to its survival. There is a ‘rich reservoir of recoverable high quality natural gas present’, but the seismic operating limit remains a barrier to developing its potential. David Attenborough and others believe that the Government should stop wasting time on this polluting industry and back the clean energy infrastructure needed to tackle climate change.
