Other mistake: The same section of the Golden Gate bridge is shown being stripped from its suspension cables twice: once when the quake hits and once when the container ship hits bottom and tips over. Also the ship cannot hit bottom, as the depth of the channel beneath the bridge is greater than 600'.
Other mistake: As Ray and Emma are drifting around San Francisco in the speedboat, they come across a Navy ship that just got carried in with the tsunami and is now leaning 20 stories high against a building with water dripping from it. If the tsunami were that high, with the wave having now receded back down to ground level, why are there still fires burning down low? The wave would have snuffed them out.
