> *yawn*. A foot and a half isn't going to be all *that* bad Sorry to continue off topic:
Try to imagine ... a temporary very high tide, rather than a cresting wave. In addition to the "height", it's the wave-length you have to take into account. Tsunami's rarely become towering breaking waves. [That said, tsunamis can form into a bore - a step-like wave with a steep breaking front. Likely if the tsunami moves from deep water into a shallow river / bay] 1 1/2 foot on top of an existing high tide, could easily cause further flooding in the wrong locations (although as mentioned, not to the levels already experienced). > travels in general at approx 970 kph (600 mph) True in the deepest parts of open ocean - upon reaching the shore-line it'll be travelling a lot slower. </off-topic> // Gav
