Corrected entry: Near the end, when the gate to Ark 4 is stuck open and water is coming in, the compartments begin sealing themselves to stop the flooding. Tamara, who was in the compartment between the daughter/dog duo and the rest of the family, wouldn't have drowned due to rising water.
Corrected entry: Even inside the ship, the water where the cast is swimming should be freezing cold, it having come from the surroundings of Mount Everest.
Correction: It was a tsunami that reached the peak of Everest, but its origin was not Everest or its surroundings. It came from the south and engulfed India first, which would make the water a lot warmer.
Corrected entry: On many occasions we see whole cities give way and fall into gigantic holes in the earth. So how can there possibly be a Tsunami that covers the whole planet? Much of the water would have poured into the enormous holes and and made it completely impossible.
Correction: Not so. Actually much of Earth's water is underground. In other words, the underground water is more than enough to replace the area left by cities sinking into the Earth. Which could actually contribute to the tsunami, not detract from it.
Most of the Earth's water is not underground, the oceans hold about 96.5 percent of all Earth's water, aquifers account for a small percentage of available water.
Recent studies have suggested that the amount of underground water can be 3 times as much as what is in the oceans. However, this water is trapped in damp ringwoodite, so it's not flowing water like you would find in aquifers.
Correction: She is never shown to die or survive the event, and is not mentioned to be either dead or alive during the rest of the film.
