Earthquakes in USA May Be Due to Fracking Techniques

Northern Texas in the past three or four weeks has experienced an intense series of earthquakes. Historically this part of America has had only two earthquakes between 1970 and 2007, but in 2008 a series of minor earthquakes were recorded and in the last few days two earthquakes, each measuring 3.6 and 2.8 on the Richter scale happened.

The geology of the region has not changed in the past forty years but human activity has changed. Fracking has been introduced and some are concerned that the increased incidence of earthquakes correlates to the increase in fracking, and that correlation may not be co-incidental.

There is no hard conclusive evidence that fracking is to blame but the evidence that exists begins to point in the direction of fracking. One earthquake researcher at the University of Texas, Cliff Frolich, thinks that waste water from injection wells could be responsible. The US Geological Survey has found that using underground storage wells to get rid of waste water in fracking is almost certainly to blame for the increase in earthquakes in the Mid West. Ohio experienced many earthquakes – so many that in 2012 the State banned fracking having taken advice that the storage of waste water from fracking underground was responsible.

Fracking for natural gas it is said will transform our economies. It may transform them in more ways than we understand.
