Fracking quakes. If anyone doesn't know, fracking is a process used to collect natural gas. One if the byproducts is waste water that gets disposed of deep underground. It turns out that this disposal process causes dozens of small earthquakes in places where they have never happened before every year. I think this is something people should be more aware of. Oh, and the flaming methane filled tap water thing is still happening too.
Fracking may cause more earthquakes than initially thought, according to an article in this weeks Proceedings of the National Academy of Sciences.
At least 59 small-magnitude earthquakes of 1.4 to 2.5 magnitude occurred over a two-year period ending in September in the Barnett Shale region of Texas that were never reported by the National Earthquake Information Center, said Cliff Frohlich, a senior research scientist at the Institute for Geophysics at the University of Texas at Austin.
Many of those earthquakes happen when fluids are injected into the ground to release natural gas, a process called hydraulic fracturing that may also relieve the friction between tectonic plates, said Frohlich, who wrote the article. The U.S. Geological Survey typically collects data for seismic events at least 3.0 in magnitude.
Rather than just looking at earthquakes when a crash happens, lets go look for ones that may not be bothering people and see if there are trends, Frohlich said in a telephone interview.
These triggered events may be exacerbated by fracking along fault lines, and differ from induced events that happen solely because of human actions, such as a man-made lake weighing down and compressing a land mass, Frohlich said.
He used seismological data from EarthScope USArray, 400 connected seismographs spaced 70 kilometers (44 miles) apart. Theyre relocated within the U.S. every two years and were in Texas from November 2009 through September 2011.
I cant study the whole country, but one field at a time I can go in and say, This is what the data say, he said.
More research on triggered events is needed to better understand what causes them and how they may be avoided, Frohlich said.
The datas freely available, he said. A junior high school student could download the data and do what I did -- if they were familiar with seismology.
