Mistakes
Many scenes showing the tidal wave approaching land and buildings is factually inaccurate. Its already stated that the tidal wave will be moving faster than the speed of sound, and reach a height of over 1000 ft by the time it hits land. That being the case, there would be a massive pressure wave of air in front of the tidal wave, that would clear a path long before the tidal wave hits. Buildings would start to topple and crumble before the water struck, and certainly people would not be able to stand in the path of the tidal wave, because the air pressure would blow them away.
