I'm sure they can come bigger than that, but "several hundreds of feet"?

If the conditions are right (like contained in a bay), you bet.

Fine.

So, an asteroid hits the Atlantic, punches a hole through the crust, and sends a wall of water a mile high straight at Florida.

It would be a bad day for Disney. I get it. It could happen.

I fished commercially outside of Lituya Bay in the early ‘80’s. My skipper would not anchor inside of this bay because of the history of giant waves (due to landslides into the bay displacing water and causing these 1700’ waves-inside the bay of course)

Instead we drifted at night between Cross Sound and Yakutat, while fishing in front of the Fairweather Glacier, as Lituya Bay is the only “safe” anchorage between the two.
