It wasn’t Fracking.
A Malaysian Airlines 777 flew into the San Andreas Fault.
They got the idea from an old Superman Movie.
The Pilot was Lex Luthor.
That's it! That's what happened.
Doesn't matter though-The LA city council will conclude that they need to ban something, tax something, or a combination of the two, to stop the earth from shaking. Then they will vote themselves a big pay raise for all their "hard work".
