Geologist James Coleman, who works for the U.S. Geological Survey, says fracking can create quakes, but not those as large as the one in Virginia.“It’s pretty clear that in some areas, underground injection of wastewater causes relatively small earthquakes, smaller than what we had here in Virginia, but disturbing to some people,” said Coleman.-Click Here For Full Story.

After Virginia's earthquake activist and people are starting to speculate this quake was brought on due to Hydraulic Fracturing. I do believe it is possible Hydraulic Fracturing could of caused quakes in Virginia. Since the halt of Fracturing in Arkansas they have had 50% less quakes. I am going to post a few videos below and articles which  show Fracturing could have caused earthquakes. What I have gathered from various sites it is not the actual drilling which causes the quakes, but the salt water that is poured into the ground to help with drilling. It is not just the U.S who also have had weird quakes due to drilling, but the UK also. Videos Below:

Fracking could have caused East Coast earthquake-"Explicitly, the United States Geological Survey has published a finding confirming that processes like fracking can be to blame for “natural” disasters. "Earthquakes induced by human activity have been documented in a few locations in the United States, Japan and Canada,” writes the USGS. “The cause was injection of fluids into deep wells for waste disposal and secondary recovery of oil and the use of reservoirs for water supplies."

Fracking Fluid Disposal Investigated As Cause of West Virginia Earthquakes-  
"Could an operation related to hydraulic fracturing in West Virginia be responsible for more than half a dozen earthquakes that have hit the state’s southern Braxton County this year? According to a report from West Virginia Public Broadcasting, one state geologists says it’s possible. "



'Fracking' Disposal Sites Suspended, Likely Linked To Arkansas Earthquakes-"The commission says there is likely a link between the wells and the earthquakes. There have been more than 800 quakes in the area in the past six months and a magnitude 4.7 quake – the strongest in Arkansas in 35 years – hit there Sunday.The high-pressure wells are used to dispose of waste water from natural gas drilling."


The Videos I am now going to share are in my opinion the best to watch when trying to understand Hydraulic Fracturing.
