If the earth did open up along the fault there would be no earthquake since there would be no friction happening when the plates move against one another. I'd have to check a map but I'm pretty sure that San Fransico is on the right side of the fault and Los Angels is on the left side since the pacific plate is moving north in this region and it's been said that LA and SF will eventually be adjacent to one another.
Correct, it is expected that SF will be come a surburb for LA. Or viceversa depending on which side of the fault line you are on.
In the movie they managed to fuse the plates at strategic points (not the whole thing), so that the Big Fault wouldn't go from Washington to Baja. Since the Southern CA bomb didn't work, the deep fault @ 700KM made the upper fault a.k.a San Andreas pretty much split open.
Now for movie purposes, the entire this was GREAT, and I personally liked it except for some of the cheesiness.
Geology wise....a 10.5 is almost implausible. Ritcher Scale only goes to 9, and since it's exponential a 10.0 would be 30K times stronger than an 8.0. 30,000 stronger than an 8.0.....what's that? Ok to put it in reference in Anchorage they said the Earth moved like water in waves of 25 feet from an 8.2 earthquake. So LADS & GENTS ... a 10.0 in geological terms means the Continental North America.... becomes an Archipelago.
Sure we have all the faults for this to happen at a lesser scale......but heck I'd be more scared of the deep hidden faults from previous geological periods...if you like this subject....do a lil research on The New Madrid Fault
...now that is scary business.
