Possibly, but most likely not deliberately, more as an accumulation of disparate legends, myths, fables and half-remembered events that seemed to fit together quite well even though they had nothing to do with each other. But this tells us nothing that we didn't previously know - we know that there was an eruption and tsunami, and we know that people told stories about Moses, exile in Egypt, and so on. All you're offering is a speculative reason, without any firm foundation, to associate them.
It can be fun to play these games, coming up with mundane explanations of fantastical Biblical events (I remember watching a similarly speculative show about the Plagues of Egypt), but it tells us nothing. It doesn't prove that this is what really happened, and it doesn't prove that the recorded events happened at all, with or without divine intervention. It's just a form of historical pareidolia, where unrelated events appear to form a wider pattern.
Are we still talking about Alpha, or has that got forgotten in all the misreported translation errors and volcano-tsunami action? Because I could say a whole lot about that.
