Subject: Re: Guess Who Actually Stole Disaster Funds
I read a hypothesis that the eruption of Santorini caused the plagues and the temporary emptying of the Red Sea. I'm sure the original article is long gone, but I did find a wiki entry about it.

Now that's an interesting conjecture. I'm not sure how it would cause the plague, but the idea that the water receding preceded a tsunami is well known. And then a long wave of water coming after that would be possible and fit the story.
