In the UK the process of fracking resulted in two small earthquakes near Blackpool. Further evidence from the US shows the increase in the number of earthquakes in areas where fracking is taking place.
Lancashire council voted today to reject further fracking at one site in the county (http://www.theguardian.com/environment/2015/jun/26/lancashire-county-council-rejects-cuadrilla-fracking-bid) but we must wait until Monday until a decision is made on an additional site.
Let’s hope that, amongst all the other health and environmental impacts of fracking, the potential to cause an increase seismic activity is taken into account.
Studies keep showing that the earthquakes start happening when wastewater from fracking is injected underground. Scientists say it’s because those large quantities of water, forced underground by heavy pressure, activate dormant fault lines. Now two more such studies have been added to the pile of evidence.
