I looked around a bit, and tend to agree with Wikipedia: A reasonable estimate for a “worst case” La Palma tsunami when it reaches the mid-US Atlantic coast is 9.6 meters.

Call it 32 ft. on the Florida east coast.

That’s still QUITE a problem, depending on the tide then ongoing, etc. Luckily, such a collapse is considered not likely, soon. (Gotta hope the “considerers” are right.)

But what if one of our enemies decide to “help” it along.

Luckily, such a collapse is considered not likely, soon.

I saw a program about the La Palma fault years and years ago. At the time, geologists claimed that the fault was steadily getting wider, though they couldn't predict when it would finally slip.

I can only imagine it's gotten wider since then. I can only imagine what a 32 foot tsunami would do to New York city.
