That seems like a bad model if it does not include the effects of the waves penetrating inland and instead acts as if the coasts are inviolable.

This particular event happened 66M years ago, it would be wild guess to include effects on land that may have or haven't existed then.

I don't see why it would be any more of a wild guess than the guess at what rock layers were hit by the asteroid and what effect they had at displacing water.

You know that ships have crew in it?

Yeah, and? How much do you think the humankind is willing to pay to save a human live - a million dollars, a billion, a trillion?

A lot more than it does at the moment, certainly. That's no bad thing either, even if insurance premiums would go up (and construction quality would then improve to compensate and bring them somewhat back down, and finally fewer incidents would result in loss of life.)

I also wonder if the model also accounts for vapourisation. Over the entire ocean, the effect may be negligible, but local to the impact may have made a non-trivial difference.

Just to put the numbers in slightly easier to imagine numbers: imagine ocean waves about 13000 feet or 4 kilometers high. No, I can't really imagine it either. In San Francisco, the tallest building is the Salesforce Tower at 1070ft. The biggest wave would be about 13 times taller than that. I totally have trouble visualizing it, other than just looking up and up and up.

I can visualize: the highest peak around me is 3200 km

m not km I presume

That’s the moon. ;-)

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?

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.

And this would be in the context of the atmosphere vaporising followed by a massive shockwave and a 10km mountain of the earths crust rising up towards the sky at the point of impact. https://www.youtube.com/watch?v=dFCbJmgeHmA

Because a few ships a year are expendable for the global economy. Not worth it to try to make every ship less sinkable - e.g. it may decrease the number of annual losses by 50% at the cost of making an average ship 10% more expensive - obviously a bad trade. Some ships will still sink, because of stuff like human errors.

The crew probably has a good idea of the risks
