The press release says that there are plans to look at inundation.

They do say that airborne water and sediment traveled several hundred kilometers.

It also has some more details about wave height: "their models indicate that open-ocean wave heights in the Gulf of Mexico would have exceeded 100 meters (328 feet), with wave heights of more than 10 meters (32.8 feet) as the tsunami approached North Atlantic coastal regions and parts of South America’s Pacific coast."

Same. Shocking to see how the waves wrapped around the peninsula though. But also, was the impact site actually ocean when it was hit, or was it flooded after impact?

It was ocean but it was sort of like hitting a shallow puddle for a 10 km diameter rock.

The article didn't say but I was also curious and looked it up on Wikipedia:

> The water depth at the impact site varied from 100 meters (330 ft) on the western edge of the crater to over 1,200 meters (3,900 ft) on the northeastern edge.

True, but it would depend on local topography/geography. I'd guess from a couple of miles up to a hundred miles inland in some places.
