Can you elaborate? Do you mean having a Tsunami is pure bad luck in Japan? (With Tsunami actually beiing a japanese word...)
I see your point though, one shouldnt go too much into 'what ifs', because all accidents are in a sense accidents/bad luck. But I still feel we can apply the what if on the outcome of the disasters, especially if it is that seasonal clear cut with high propability.
Related hypothetical: if a hydroelectricity dam failed when hit by an earthquake stronger than the one it was designed for, how much of a pass would we give Hydroelectricity?
