That would be literally unprecedented in what we know of geologic events. It would require a quarter of the circumference of the Pacific plate to rupture all at once, with the rest of the plate behaving nearly completely rigidly: simultaneously weirdly weak at the edge and stupid strong everywhere else. Considering that the plates aren't that different between the edges and centers (including intraplate faults and weak zones), this is profoundly unlikely.

I'm not saying it could never, ever happen- but it's far more likely that a Hollywood movie featuring the above disaster as a plot and a cast of D-list actors will sweep the Oscars. Don't lose sleep over this.
