The asteroid that wiped out the dinosaurs caused a tsunami 4.5 kilometers high.

Scientists at the University of Michigan conducted the most detailed collision simulation to date. The traces of waves in 120 rock samples around the world were taken as the basis. And it was revealed that the first tsunami wave reached a height of 4.5 kilometers, and the second - 1.5. If this happened now, on Earth, too, few would have survived.
