In seismic terms, North Dakota is definitely a better bet than California, but the potential for earthquakes is virtually universal. Fracking is on the increase in ND, and there do seem to be some rather strong correlations between fracking and earthquakes, some of which reach in Richter 4 and 5 levels.

Earthquakes remind us that life is unpredictable and that many events are beyond our control. Sometimes the best we can do is play the odds, prepare for the worst, and hope for the best.

Incidentally, the nascent earthquake warning system worked for this event. Although a longways from full implementation, it did give some advance warning...It will get better in the future.
