As cool as that is, I'm more interested in seeing how far inland the waves would go.

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?

There are a large number of events taht have happened many times in Earth's history and, given the cosmic timelines, will happen again, repeatedly. Some may be preventable with technology (eg asteroid impacts), others less so.

A partial list is: tsunamis, earthquakes, volcanoes, supervolcanoes, flood basalts, asteroid impacts, magnetic field reversals, climate change (eg ice once covered the equator, North America used to be covered in an ice sheet a mile thick not that long ago), particles in the atmosphere blocking the Sun, supernovas, gamma ray bursts, solar flares and coronal mass ejections.

It's kind of amazing we're here at all.

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.

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

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

More amazing to realize without any of those things we wouldn't be here!
