I figured this topic would really take off, and, well, I *am* surprised. :’)
FWIW, it is actually a very interesting thread. After reading the article I went off on a search spree for other articles on the subject. I wanted to find out why we haven't seen more of this type of work and why there hasn't been numerous discoveries of tsunami evidence in an area austensibly disposed to this sort of thing. Spent SEVERAL hours doing that and wandered off into some peripherally related stuff. Apparently it's going to take a while for evidence of catastrophes during historical times to catch on.
