Corrected entry: Near the end of the film, Chief Ray Gaines is desperately trying to save his daughter, Blake, from rising water inside a building. The water engulfs them both at the exact same moment, and Ray watches helplessly as Blake immediately drowns without struggle in only 22 seconds. However, virtually anyone can hold his breath much longer than that, up to two minutes or more. In fact, Ray continues holding his breath for an additional 30 seconds under continuous physical exertion as he retrieves Blake's body and swims to the surface.Charles Austin Miller
Corrected entry: Tsunamis are caused when the epicenter of the earthquake is located in the sea. Physically, in order for a tsunami to be formed, the seabed must move abruptly in a vertical direction. In this movie, all the earthquakes are located inland, along the San Andreas fault.
