Fracking is bad for the earth and everything in it and on it....we need to knock this off. It figures that Darth Cheney had a hand in it...

A U.S. Geological Survey (USGS) team has found that a sharp jump in earthquakes in America's heartland appears to be linked to oil and natural gas drilling operations.As hydraulic fracturing has exploded onto the scene, it has increasingly been connected (http://thinkprogress.org/romm/2012/03/09/441812/ohio-finds-fracking-waste-injection-well-caused-earthquakes/)to earthquakes. Some quakes may be caused by the original fracking — that is, by injecting a fluid mixture into the earth to release natural gas (or oil). More appear to be caused by reinjecting the resulting brine deep underground.

Last August, a USGS report (http://www.ogs.ou.edu/pubsscanned/openfile/OF1_2011.pdf) examined a cluster of earthquakes in Oklahoma and reported:
Our analysis showed that shortly after hydraulic fracturing began small earthquakes started occurring, and more than 50 were identified, of which 43 were large enough to be located. Most of these earthquakes occurred within a 24 hour period after hydraulic fracturing operations had ceased.

In November, a British shale gas developer found it was "highly probable" (http://thinkprogress.org/romm/2011/11/02/360014/shale-fracking-earthquakes/)its fracturing operations caused minor quakes.
Then last month, Ohio oil and gas regulators said "A dozen earthquakes (http://www.usatoday.com/money/story/2012-03-09/fracking-gas-drilling-earthquakes/53435232/1) in northeastern Ohio were almost certainly induced by injection of gas-drilling wastewater into the earth."

Now, in a paper to be deliver at the annual meeting of the Seismological Society of America, the USGS notes that "a remarkable increase in the rate of [magnitude 3.0] and greater earthquakes is currently in progress" in the U.S. midcontinent. The abstract isonline (http://www2.seismosoc.org/FMPro?-db=Abstract_Submission_12&-sortfield=PresDay&-sortorder=ascending&-sortfield=Special+Session+Name+Calc&-sortorder=ascending&-sortfield=PresTimeSort&-sortorder=ascending&-op=gt&PresStatus=0&-lop=and&-token.1=ShowSession&-token.2=ShowHeading&-recid=224&-format=/meetings/2012/abstracts/sessionabstractdetail.html&-lay=MtgList&-find). EnergyWire reports (http://www.eenews.net/energywire/print/2012/03/29/1)(subs. req'd) some of the findings:

The study found that the frequency of earthquakes started rising in 2001 across a broad swath of the country between Alabama and Montana. In 2009, there were 50 earthquakes greater than magnitude-3.0, the abstract states, then 87 quakes in 2010. The 134 earthquakes in the zone last year is a sixfold increase over 20th century levels.

The surge in the last few years corresponds to a nationwide surge in shale drilling, which requires disposal of millions of gallons of wastewater for each well. According to the federal Energy Information Administration, shale gas production grew, on average, nearly 50 percent a year from 2006 to 2010.

The USGS scientists point out that "a naturally-occurring rate change of this magnitude is unprecedented outside of volcanic settings or in the absence of a main shock, of which there were neither in this region." They conclude:
While the seismicity rate changes described here are almost certainly manmade, it remains to be determined how they are related to either changes in extraction methodologies or the rate of oil and gas production.

We don't need this kind of energy development.

Moon increases earthquake intensity...
Moon Phases Linked to Big Quakes
September 12, 2016 - Full moons may cause bigger earthquakes, according to a new study.

Researchers at the University of Tokyo say large quakes are more likely during high tides, which happen twice a day. During high tides, the oceans are pulled by the moon’s gravity, but during a full and new moon, twice a month, the tides are particularly high, especially when the moon, sun and Earth line up.

This, researchers say, can further stress geological faults, triggering earthquakes. “The probability of a tiny rock failure expanding to a gigantic rupture increases with increasing tidal stress levels,” the researchers wrote on an article that appeared in the British journal Nature Geoscience.

While the theory is not new, the study is the first to find a statistical link between the moon and earthquakes. For example, the researchers found that the 2004 Sumatra quake as well as a major 2011 quake in Japan both happened during high tides. The researchers say nine of the 12 biggest quakes ever recorded were timed with full or new moons.

The findings could help with earthquake forecasting, especially in places like Japan where earthquakes are common. "Scientists will find this result, if confirmed, quite interesting," said University of Washington seismologist John Vidale, who was not involved in the study. But he added that "even if there is a strong correlation of big earthquakes with full or new moons, the chance any given week of a deadly earthquake remains miniscule."

Apparently there is a connection to earthquakes and fracking to a point where the U.S. Geological Survey is concerned; Induced Earthquakes (http://earthquake.usgs.gov/research/induced/)
