Tsunami that devastated the ancient world could return

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.

Hey... We just had a tsunami a couple of years ago that took the lives of 250,000+ people. How often is an event like that going to happen in the course of 10 life times?

The answer is - Not a whole heck of a lot.

Relax! If you’re scared of the sea move away from it.

With an area covering four-fifths the surface of the earth, we should respect what power it may possess.

In 2006 I moved to Kentucky, after forty years in Florida. So far it hasn’t been a mistake.

A toon could drop an anvil on our heads also.

All the Great Tsunami prophets are going to feel so silly when it’s Sky Fall that gets em.

This has been debunked by a consensus of tsunami scientists. …collapse of La Palma

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.

Tsunami warning in the Mediterranean wouldn’t be worth much. Distances are too short.

[Man50D]

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.

It seems to me you are comparing apples to oranges. Your body is not generating a wave extending down to the ocean floor. It is only creating a surface wave. The debris from a massive landslide will reach the ocean floor and therefore generate a tsunami that extends down to the ocean floor as does an earthquake generated tsunami. Some energy will be lost reducing the initial height from 300 feet down to 165 feet but there isn't enough friction between La Palma and the U.S. to dissipate the tsunami.

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.

There is one factor you're not considering with respect to NYC. Long Island Sound narrows as you move towards NYC. The narrowing of Long Island Sound along with the rising ocean floor may very well push the wave height of a tsunami to at least 165 feet and possibly higher.

Interesting.

Mother earth just doing her thing.

"Repetition of such an event would have catastrophic consequences for today's densely-populated Mediterranean coastal regions."

Oh, the asteroid will hit us and destroy all life on Earth before that ever happens...

"(I wonder where it has been hiding all this time.)"

Maybe the Bush administration borrowed Wesley Clark's time machine to go back and suck it up into Rove's weather machine so they can unleash it on the masses...to profit Halliburton, of course.

[Larry Lucido]

Yes, but nobody in 364 AD got hit by a bus, so it’s not significant.
