nowwhat,
The devestating eartquake that triggered the tsunami and the Fukushima nuclear plant disaster was a magnitude 9 earthquake and the waves were caused by shifting of the ocean floor by no more than 50 ft vertically.
Can you even begin to imagine what would happen if mountains were pushed up by even several hunderd feet? Let alone by thousands or tens of thousands of feet?
You think the waves caused by a "mere" 50 ft shift that carried and threw around container ships like toys, you think those waves or even bigger waves caused by bigger shifts in tectonic plates would let a bronze age wooden box (not seaworthy, but that's a different problem alltogether) still float around?
