Cuadrilla Resources have just sent me this slide on earthquakes.  

They've had the bad luck to have an earthquake that has been mentioned by the press worldwide.  They made the front page of the Houston Chronicle with the 1.5 quake when I was there in late May for one example, and a google search of UK Shale Earthquakes will get you 225,000 results, few of them with much bearing on reality

 It just serves to confirm one of our many fears about shale gas. As well as the earth tremors, and concerns over ground and surface water contamination attributed to shale gas drilling, there are of course also the greenhouse gas emissions associated with its extraction and the consequent burning of what is yet another carbon-emitting fossil fuel.

The key word there is fear. And in that case earth tremors sound much scarier than greenhouse gas emisions

Back in 2008,  there was Britain's biggest earthquake in 24 years.  It released 3,990,643 megajoules of energy. As the  Telegraph points out, 

 Insurers are facing a £30 million payout after the earthquake that shook large parts of Britain in the early hours.

They are continually looking on the dark side of life at the Telegraph.  Over at Bloomberg which one would think more interested in money:

 `It doesn't look like there's been an awful lot of damage at this stage,'' Jonathan French, a spokesman for the Association of British Insurers said today in a telephone interview.

Therefore, apart from the cost to life and limb

 A 19-year-old man in Wombwell, northern England, suffered an injury to his leg when he was hit by bricks from a chimney

each megajoule of energy released according to the probably hysterical Telegraph figures caused 7.5 pence worth of damage. Which means the true shocking cost of the 1.5 Lancashire earthquake was slightly over a dollar.
