I assume it would just flood all of FL
a couple of computer simulations for other areas
What would happen if New York City was struck by a La Palma mega tsunami? Computer simulation shows the effects of a 20 m wave arriving there from the Southeast.

The real evidence was studied by the USGS years ago and at the very MOST, the wave height would be around 20-40 feet high, which will be catastrophic in itself. So, think the boxing day catastrophe.
And that was for a HUGE landslide which wont happen.
The further away the wave travels to less in height it is.
Now the east coast of Africa? And the coasts of Europe? That is another matter.
Those are both Subduction type tsunamis - Subsidence (the sort La Palma would create) causes standing waves which do NOT dissipate until they strike a landmass equal or higher than the wave, else they just continue over land until the energy is expended.
videos are worthless.
