In reality, and according to many earthquake experts, the biggest quake that this fault could produce is an 8.3 and, being a land and not ocean fault, cannot cause a tsunami. Or as consultant to the film Tom Jordan, director of the Southern California Earthquake Center stated, "I gave (the filmmakers) free advice, some of which they took... But much of which they didn't - magnitude nines are too big for San Andreas, and it can't produce a big tsunami."

Whereas the MRI shown by Gracie reveals several abnormalities like brain atrophy and degeneration due to complications of previous disease process. (00:27:45 - 00:28:30)Ganesan Krishnan
