Hm, I have much more difficulty imagining how far inside the shoreline that would go - so if I take a port city, is it wiped off completely? Does it matter if it goes uphill for 10km? 100km?
I was wondering the same. the simulation doesn't appear to account for the landmasses, treating them as impenetrable barriers. where is the flooding simulation? are we to assume the shores were 5km high vertical rock?
One of the science show (Nova ? could not find it quickly) did an extinction event analysis on a point far upstream a river and tied it to the Chicxulub event. The local flora and fauna were killed by water flow high up river and hot ash rain.
