The volcano collapse would also seriously affect the UK.

The Scotsman

The wave-front from the collapse would spread out in a crescent, striking the west African coast with a wall of water more than three hundred feet high in two to three hours.

Its northern side would also brush against Europe. Within three to four hours, a 33ft high wave would smash into the south coast of England, causing immense damage.

Unlike a normal wave, the tsunami would not break rapidly but just keep coming, said Prof McGuire.

“You’re not talking about the destruction of the UK economy, but very serious damage along the south coast,” he said.

Trying to stop the mountain collapsing was simply out of the question, he said.

He had done a calculation which showed it would take 35 million years to dig out the dangerous part of the volcano and move it away.

I saw that on National Geographic Channel.
I sure hope they make good work of monitoring that volcano, not only to check when it might slide, but emagine this:

A Terrorist organisation sees the same Documentary as we did. He sees all those nice places in the middle of nature where noone would be able to monitor him and his palls and gets the most brilliant idea a terrorist could get.

He gets some buddy's of his together and starts planning where to put charges along the breach in the volcano, on the TV show alone I saw a douzen places noone would ever see you do your thing and heck, if they did see, you could act asif your a research team doing drills to check the place out.
He assists nature in letting the volcano slide, its already ready to slide, so not much explosive power is really needed to make it go.

Next thing you have a 100 meter high tsunami making its way to the US and a whooping lot of other places. When it hits, really big $hit hits the fan on the US coastline.

The US shouldn't be pushed to monitor that place. They should be doing it already. Its a place outside of US soil that if used by terrorists could mean utter catastrophy comming their way.

Reading the paper Tanin posted you can see that the volume of rock they are talking about is on the order of 150 to 500 cubic kilometers. If it is mostly Basalt, density ~ 3.3 g/cc, that's 3.3x(150 to 500)x(1,000,000cc/cubic meter)x(1,000,000,000cubic meters/cubic kilometer)/(1000 g/kg)=3,300,000,000,000x(150 to 500)=495,000,000,000,000kg to 1,650,000,000,000,000kg. Divide by 2.2 kg per pound, that's 2,250,000,000,000,000 to 750,000,000,000,000 pounds or 1,125,000,000,000 to 375,000,000,000 tons of rock. Thats a big rock. Aint no nuke gonna move that baby. When it goes, it will go with great enthusiasm, and aint no one gonna stop it. There is another paper out there, I found it last week, but I can't seem to locate it today, describing a series of experiments investigating the creation of waves using this type of mechanism, albeit on a somewhat smaller scale. Results support the conclusion that if this baby goes, you best be well inland. Hope my math is right above, shouldn't be too far off.

But, what they are not telling you is that there are methane in deep-sea reservoirs. Some are of the coast of Africa. And the said landslide would cause the release. Some believe that these gasses stopped the Ice age.


A hot theory about how the Ice Age ended has got a frosty response at a meeting of the leading European and American geoscience societies in France.
news.bbc.co.uk...


Also, may have killed all of prehistoric life.

Huge reservoirs of methane trapped beneath the ocean floor rapidly escaped during prehistoric global warming and depleted much of the sea's oxygen, according to new research into why many forms of life suddenly vanished 183 million years ago.
www.cnn.com...

Methane is a highly potent greenhouse gas. In its solid, ice form, called methane hydrate, it is stored in large amounts below the sea floor. Some signs indicate that there have been repeated intense undersea methane emissions over the course of the Earth's history. Often, these emissions appeared to be linked to climate changes, species extinctions, and biological cataclysms both in the oceans and on continents. In the coming issue of the journal Science, Prof. Kai-Uwe Hinrichs from the DFG-Research Center Ocean Margins Bremen/Germany and his colleagues from Woods Hole Oceanographic Institution (WHOI) present new insights related to methane emissions in the recent past. According to Hinrichs, who was only recently appointed to the Bremen research center, multiple rapid, intensive eruptions occurred in the warmer phases of the last ice age on the North American Pacific coast. Undersea melting of methane ice and landslides could have been the causes of these events, which resulted in oxygen depletion in the ocean.

Thanks for the interesting computation. You are right about the mass. However, there some really big nukes out there (100 megaton ones) that are capable of demolishing this kind of rock. This has been done in Russia on one of their northern islands (most of which was literally evaporated).

Of course, a nuke of that caliber would create a tsunami wave itself


So there is catch 22 here for sure.
