    1. Sat. 10/20/12 close to 12a.m., we heart a loud boom, a huge jolt hit, then the windows shook and pictures moved, not lasting more than 10-20 seconds. We live N.W. of Lemoore in the country. I believe, without a doubt, that Fracking taking place inbetween Monterey counties and the Central Valley (in close proximities to the San Andreas Fault), absolutely play into all the quakes. Wake up California!

    2. We reside N.W. of Lemoore in the country, approximately 2miles to the back entrance of NASL. 30 miles S.W. of Fresno, while we were watching a movie in bed we felt a huge jolt to the house and a loud boom. The windows rattled, the walls and pictures shook, and then we felt the shifting of the earth beneath the house. I continued to feel aftershocks after the initial quake for 10-20 seconds. An area close to the San Andreas fault line, Fracking is taking place, inbetween Monterey, Monterey county and the Central Valley. In fact, it is happening throughout California. Without a doubt, I also contribute Fracking is a huge factor as to the number of earthquakes California is experiencing, as well as other states were Fracking continues. Wake up California, ban Fracking!

      • Armand Vervaeck says:

        In some states and areas fracking is the origin of earthquakes. In the current earthquake this is simply a faulting generated earthquake. Additionally fracking is only responsible for minor earthquakes so far.
