There were earthquakes along that major fauly in 2008 and 2009 before fracking even started there. There is some research that the quakes during the process was caused by salt water disposal wells drilled in the area but the studies have determined that it had nothing to do with fracking. The very name MAJOR STRESS FAULT tells you quakes are just a matter of time. It's a good thing you are not the one educating us as the words are pressure not presser, released not reliced, principal npt prenciple and research not reserch. Perhaps these misspellings are the reason the sites you go to for information are full of quack science as real scientists probably can spell the words correctly.
