A new federal investigation reveals a spate of earthquake activity in certain regions of the U.S. is likely the cause of localized hydraulic fracturing (fracking) drilling for natural gas and oil.

Dear BiggerPicture,
The USGS is the same group that previously said that the earthquakes were normal. It is very doubtful that fracking is causing the quakes. We set off thousands of nuclear bombs underground in Nevada and it didn't cause quakes. I want to see a correlation showing how many of these quakes were nowhere near fracking operations and how many were. 50 out of 8,000 is nothing. There was no fracking going on in Haiti or Japan. Look at how many large quakes have happened in places where no fracking is going on.
The video did not say that fracking was the cause of 100% of the earthquakes. Obviously, there was no fracking going on in Haiti or Japan. Fracking was never said to be the cause of ALL earthquakes. Seeing how many earthquakes are/were located near fracking is a valid, though; I agree there. But you can't discount fracking just because it didn't cause earthquakes in locations where there was no fracking happening.

According to their 990 tax forms, the Environmental Working Group’s total revenue was more than $6.2 million for 2008. Over $3.2 million of that was distributed to the group’s board members: $219,401 to president Kenneth Cook; $179,218 to executive director Richard Wiles; and $150,226 to director of research Jane Houlihan. Five more board members racked up six figure salaries. Another $2 million was distributed to other employees, and almost $300,000 was put into pension plans and other benefits packages.
The EWG raises the vast majority of its money – $6 of the $6.2 million – from various philanthropies, most of which have a distinct leftward bent and seem to be more interested in influencing public policy than doing real scientific work, and individual donations. In 2009, for example, they received $300,000 from the Popplestone Foundation (a major donor to liberal think tank the Center for American Progress and liberal magazine the American Prospect), $50,000 from the Winslow Foundation (who supports, among other projects, Grist.org, a group fighting “the climate apocalypse”) and $75,000 from the Keith Campbell Foundation for the Environment (a major funder of the Center for Progressive Reform).
In 2008, they received $85,000 from the Turner Foundation (liberal billionaire and CNN founder Ted Turner’s philanthropy) and $250,000 from the Joyce Foundation (which gave millions of dollars to discredited community organizers ACORN and has fought to outlaw private ownership of handguns). One could go on in this fashion, but hopefully you get the point: There’s big money to be had from leftwing philanthropies if you’re in the business of scaring people about health issues and the environment.

Please show where "USGS now admits" that any earthquakes are caused by fracking.

Q: Does the production of natural gas from shales cause earthquakes? If so, how are the earthquakes related to these operations?
A:
To produce natural gas from shale formations, it is necessary to increase the interconnectedness of the pore space (permeability) of the shale so that the gas can flow through the rock mass and be extracted through production wells. This is usually done by hydraulic fracturing ("fracking"). Fracking causes small earthquakes, but they are almost always too small to be a safety concern. In addition to natural gas, fracking fluids and formation waters are returned to the surface. These wastewaters are frequently disposed of by injection into deep wells. The injection of wastewater into the subsurface can cause earthquakes that are large enough to be felt and may cause damage.

Too bad.
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. 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.
I am not sure I understand what you are blasting? Youtube?
theres obviously only so much drilling and prodding the crust beneath our feet can take before it starts giving in. oh wait, it already is:
Importance of small earthquakes for stress transfers and earthquake triggering is a study published on the Cornell University Library database which indicates just that possibility:
The stronger the spatial clustering, the larger the influence of small earthquakes on stress changes at the location of a future event as well as earthquake triggering. If earthquake magnitudes follow the Gutenberg-Richter law with b>D/2, small earthquakes collectively dominate stress transfer and earthquake triggering, because their greater frequency overcomes their smaller individual triggering potential.
This is telling us that even though each individual quake represents only a small amount of energy release, the cumulative effects are more than the sum total. In other words there is a possible synergistic effect with a multitude of small quakes on a (non) related fault system within a certain geographical area.
Why hasn't this been given more research?
Because large earthquakes modify stress over a much larger area than smaller ones, and because computing Coulomb stress changes requires a good model of slip distribution available only for large earthquakes, most studies have neglected the influence of “small” earthquakes.
So, how does this influence propagate into a fault system?
• A triggered earthquakes size is independent of the magnitude of the triggering event (“mainshock”) as suggested by [Helmstetter, 2003]. This implies that the crust is everywhere close to failure, such that any small earthquake, triggered by a previous small one, can grow into an event much larger than its trigger
As one takes notice of the rifts that circle the globe and then thinks about the fact that there is spreading taking place around the globe, one cannot help but conclude that all of the that spreading is going to be causing pressure to increase in areas which are being "crowded." This results in a globe who's surface is everywhere fractured, thus on the point of rupture at any given time with no prior notice.
What does all of this mean?
emphasis mine
These results imply that a small earthquake can trigger a much larger earthquake. It thus validates our hypothesis that the size of a triggered earthquake is not determined by the size of the trigger, but that any small earthquake can grow into a much larger one [Kagan, 1991b; Helmstetter, 2003; Felzer et al., 2004]. The magnitude of the triggering earthquake controls only the number of triggered quakes
So, smaller quakes can trigger larger quakes and it is merely the number of quakes triggered, not size of subsequent quake which is affected when considering remote triggering.
It all boils down to this:
emphasis mine
Although large earthquakes are much more important than smaller ones for energy release, small quakes have collectively the same influence as large ones for stress changes between earthquakes, due to seismic spatial clustering.
Since smaller quakes occur in a more compact area, they have influence equivalent to larger quakes due to the closer proximity to one another.

Oil giant Total has moved to reassure investors and environmental activists over the past week that the financial and environmental damage from its gas leak in the North Sea would be limited, a task made more difficult by comparisons to BP's handling of a catastrophic oil spill in the Gulf of Mexico nearly two years ago.
There is already enough pressure on fault lines without us try to put more there. Ohio is on the north eastern edge of the New Madrid fault line. Major quakes on that line have been felt as far away as Charlestown, New York and Boston. This fault system is ten times as large as the San Andres Fault system. In a report filed in November 2008, The U.S. Federal Emergency Management Agency warned that a serious earthquake in the New Madrid Seismic Zone could result in "the highest economic losses due to a natural disaster in the United States," further predicting "widespread and catastrophic" damage across Alabama, Arkansas, Illinois, Indiana, Kansas, Kentucky, Mississippi, Missouri, Oklahoma, Texas, and particularly Tennessee, where a 7.7 magnitude quake or greater would cause damage to tens of thousands of structures affecting water distribution, transportation systems, and other vital infrastructure. The earthquake is expected to also result in many thousands of fatalities, with more than 4,000 of the fatalities expected in Memphis alone. We are asking for trouble with this extremely dangerous gamble for fossil fuel, when the answer is right above us. Solar energy plants utilizing molton sodium will generate electricity 24/7
In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement along the fractures as a result of earth movement. Large faults within the Earth's crust result from the action of tectonic forces. Energy release associated with rapid movement on active faults is the cause of most earthquakes...
