Science behind the Exodus tales

Did a volcanic eruption enable Moses to "part" the "Red Sea"? Titanic/Terminator director James Cameron is executive producer of a new documentary examining the natural phenomena that may have inspired Exodus. From The Sunday Times:

In The Exodus Decoded, a 90-minute documentary that will be shown in America this month, Cameron and Simcha Jacobovici, the Canadian film producer, claim a volcanic eruption on the Greek archipelago of Santorini triggered a chain of natural catastrophes recorded in the Bible as the 10 plagues that God visited upon Egypt as punishment for enslaving the Jews.

Cameron believes the parting of the Red Sea may have been a tsunami that destroyed the pharaoh’s army as it pursued the escaping Jews. The documentary claims the episode occurred not at the Red Sea but at the smaller Sea of Reeds, a marshy area at the northern end of the Gulf of Suez. An underwater earthquake may have released poisonous gases that turned the waters red.
