An active Volcano called Cumbre Veija erupted in 1949 causing a partial collapse of a major portion of the island's western flank. Another eruption occurred in 1971. An eruption some time in the future will cause a total collapse sending a wave 300 feet high across the Atlantic at a speed of approximately 500mph. It will strike the entire eastern seaboard. The wave height, by some estimations, will be 165 feet by the time it reaches the east coast and move upto 12 miles inland.

This has been debunked by a consensus of tsunami scientists. Media didn't bother to tell you that, because it isn't exciting. Any collapse of La Palma would create only a local tsunami. Collapse tsunamis actually don't propagate long distances nearly as well as earthquake tsunamis, though they can be very high locally.

If not, it would seem like a good terrorist target. Detonate enough explosives to send La Palma into the ocean. Stuff for movies.

I watched a program about La Palma and wondered if its collapse could really generate 165 foot wall of water to hit the East Coast.

When you think about it, dropping a large heavy object into water will generate a wave but its effect is local and it dissipates rather quickly given a large enough body of water.

So if I do a cannon ball into the middle of a small pool, the wave created will hit all sides of the pool. But if I cannon ball into a larger and deeper body of water like a lake, it won’t even cause a noticeable ripple on the opposite shore.

Of course a mountain falling into the ocean will displace a lot of water and make a darn big splash and cause massive damage to any nearby islands and local shipping, but I’m a little skeptical that NYC would be inundated by a 165’ wall of water.

Who are these so called consensus of scientists?

Media didn't bother to tell you that, because it isn't exciting.

And neither did you. You're vague and general statement lacks any credibility without citing the very sources you claim dispute a landslide generated tsunami.
