It must be caused by fracking because it is difficult (but not impossible) to blame “extreme conditions” like earthquakes on man-made global warming.
One would think so. But recall that last year, a CNN anchorwoman (Deborah Feyerick) asked on-air if global warming was causing an asteroid to pass so close to earth.
Maybe it didn’t cause this one, but how smart is it to do fracking on/very close to earthquake fault lines? Kind of like how smart was Japan to build a nook plant on earthquake fault lines.
And it seems proven that fracking does cause quakes in areas not known for seismic activity. Ohio.

And Oklahoma.
“From 1975 to 2008, the US Geological Survey found that central Oklahoma experienced one to three 3.0-magntitude earthquakes per year, The Nation reported. That number jumped to an average of 40 a year from 2009 to 2013.”

So why do we tempt fate to frack in highly earthquake prone California. Is possibly saving a penny on a gallon of gas worth risking millions of lives? I imagine some would say yes. Not to mention the gigantic waste of freshwater. Last I heard California is in extreme drought.
