Hard to have more than crickets from somebody who can't have a normal discussion. We all get a little "locked in" to what we think is the right answer at times..I am guilty as well, but TVA is usually like that. This one isn't about personal experience, it is about probability through tiime of things that don't normally happen. Earthquakes can happen anytime, anywhere albeit with different probabilities in different areas. Storm surge is dependent on the weather and location which is WAY more predictable even though obviously not 100%.
