As the above maps make clear, the two earthquakes that hit the east midlands in the last 24 hours are prime UK fracking areas. Either fracking is already taking place there, or it is planned to very soon. Now “experts” are warning us that we should expect more earthquakes here in the UK because there could be a “hidden fault line”. What utter bullshit. In the US, most notably the Barnett Shale area around Dallas-Fort Worth, fracking has already been linked to several earthquakes.
Many experts believe that it isn’t the drilling that causes the earthquakes, but rather the disposal wells. Disposal wells are located thousands of feet underground, encased in layers of solid concrete, and are the final resting place of used drilling fluid.
“The model I use is called the air hockey table model,” says Cliff Frohlich, a research scientist at the Institute for Geophysics at the University of Texas at Austin. “You have an air hockey table, suppose you tilt it, if there’s no air on, the puck will just sit there. Gravity wants it to move but it doesn’t because there friction [with the table surface].”
But if you turn the air on for the air hockey table, the puck slips.
“Faults are the same,” he says. If you pump water in a fault, the fault can slip, causing an earthquake.
“Scientists in my community know that injection can sometimes cause earthquakes,” Frohlich says.
An earthquake has struck the Rutland area of the East Midlands again, just 24 hours after a similar tremor shook houses for ten seconds.
Initial data released by the British Geological Survey (BGS) said the latest 3.5-magnitude quake, the biggest in the region since October 2001, struck the Oakham area at around 7:50 am today.
Yesterday’s 3.2-magnitude quake occurred at 7:07 am and reportedly shook houses.
The UK is not itself generally associated with earthquakes.
However, according to the BGS, 20 to 30 tremors are felt every year, while a few smaller ones are tracked by sensitive instruments.
While most are small and cause no damage, there is the potential for larger ones in future
