    I think this was from a movie. What would happen if you put a BIG bomb in the heart of 10 key volcanoes and detonated them at the same time? Would the earth blow apart?

    I think gravity is a bit too strong to allow that to happen. It might however make a major mess out of the surface. Let's not try it

    Volcanos are very complex structures. The outward pressure of the planet's core is many times stronger than any bomb you would place in it. Most likely, you would just see the mountain expand a bit, and see a lot of dust wave up from the surface. Though we may think we are powerful, we barely have enough power to shake the foundation of the earth, actually.

    In any case, a carefully placed bomb in some volcano somewhere could send a mega-tsunami, a big tidal wave, to collide with the US east coast in about 8 hours. The effect would be 'Day After Tomorrow'-like.

    Still, I don't expect we will be able to contruct a bomb big enough to do anything but dent the surface. We do have the capablities to whipe out the human race though .

    The bombs would have to be considerably bigger than any bomb currently developed. The Earth is pretty big...

    Interesting that you mention this. I saw a Discovery Channel show this weekend about volcanoes on an island in the Atlantic Ocean (Las Palmas maybe? Can't quite recall the island's name) where this very scenario was developed and is likely.

    Vulcanologists have found that the volcano cone is porous allowing rainwater to seep down into the volcano's core. There are vertical columns of cooled magma that are not porous so the rainwater has been trapped insided the volcano in huge "silos". When an eruption occurs (about every 200 years on average), the water is superheated into steam almost instantly and literally blows the side of the volcano and most of the island into the ocean. This will, they suspect, cause a huge tidal wave several hundred feet tall that hits the East Coast about 8 hours after the eruption.

    There are two volcanoes on the island - one extinct. This already happened to the extinct one quite some time ago. Because it's extinct, geologists were able to dig into it and disocver the water and magma "silos".

    Yeah, that was the scenario I was referring to! Sadly however, Europe will also be affected, so I didn't place any bombs . Doom scenarios have always fascinated me. Sometimes, as I sit before my computer, I see '19th century'-archeologists analyse a super-advanced computer, thinking it is a sculpture, and putting it in a museum. I wonder what will be left of our culture, should we be destroyed, and future men start digging...

    lol at discovery channel, by the way, I have seen that program rerun multiple times. They really should start making new programs .

    How much damage would a tsunami that size cause?

    I just did a rough estimate of a 200m x 200m x 200m body of water travelling at 31.3 m/s and hitting a building. This is approximately 11.3million N/m^2
    1 Newton is approx .25lb, so that is approx 2.8 million lbs on every square meter. I'm going to let you all take a guess what kind of damage that would do to the east coast.

    That's like a nuclear bomb going off next to it

    The damage caused by generation of a tsunami from a portion of Las Palmas falling into the ocean depends greatly upon the direction and force with which the ocean is displaced. If you consider the geometry of the island's location and the probable propagation of the wave energy, most affected would more likely be Canada, Greenland, Ireland, the UK, Spain, Portugal, France, portions of N. Africa, the Caribbean Islands, and South America. Compare the locations of reported tsunami in the Indian Ocean region following the 9.0 earthquake in which a large portion of the earth's crust was displaced and it becomes obvious that the topography of subterranean structures has a great affect on wave propagation. Also keep in mind that the volume of the whole island of Las Palmas is a fraction (at 50 km across about 1/10th) of the amount of earth displaced around Sumatra.

    Hey Netmeister, welcome to the forum.

    I've been keeping up on the news on the Asain Tsunami. Unreal what kind of damage and loss of life these things can cause. Death toll was up around 120,000 last time I checked. That's insane.

    To see a representation of how the tsunami wave propagated from the earthquake site check this site:

    pmel.noaa.gov/~tsunami/sumatra/indo2004.mov

    You'll notice how some landmasses were protected from the force of the wave by other subteranean structures. Something else to note, you can see how the wave passed by some smaller coral structures in the western part of the IO. Deigo Garcia (just south of the equator) was unaffected by the effects of the tsunami largely due to a lack of a sloping beach or landmass (continental shelf).

    Pretty cool info, perhaps we should start a thread on the tsunami itself.

    In the cheesy 60’s movie A Crack in the Earth the world was threatened by a fast spreading crack that threatened to split the earth in half. Humanity was saved when quick thinking scientists detonated a nuclear bomb in a volcano (or was it a bore hole?) The explosion redirected the crack which circled back on itself. A chunk of the crust was blown into orbit to become a second moon by the steam explosion triggered by the massive amounts of sea water that became superheated in the mantle. Humanity was saved and we all lived happily ever after.

    Okay, just say there was no crack to begin. Would a good sized explosion in the heart of a volcano, or deep in a bore hole threaten the stability of earth?

    Doubtful, the earth's crust has been pounded from outerspace (lots of holes in terra firma from comets or meteors landing) or from man's detonation of nuclear weapons deep in the earth and the crust still stands. Anything man has come up with pales in comparison to what the earth does on its own.

    An interesting note to add about the Island La Palma, or whatever it is called, is that the actual fragment of the island does not represent the size and power of the (Mega-)Tsunami.

    The biggest power of a Mega-Tsunami is that a a vaccuum of air is created, which is many times larger than the actual piece falling off. This means that if the ocean is very deep at the La Palma area, is that there will be a whole lot of 'air-vaccuum', and thus a tremendous force.

    Swiss analysts said the wave would probably reach 20 (either kilometers or miles, I can't remember) landinward at the US.

    Still, things like these are heavily subject to the Chaos theory. Hell, the mere presence of a whale could have a huge impact on the final outcome. However, if a terrorist really wants to kill loads of people, he'll know where to strike. So.. Who's for permanent protection for La Palma? :P

    Here's a listing of the volcanoes found in the Canary Islands. Which one do the Swiss analysts say is going to cause the big blow? I'd like to look at their data.

    NAME LAT LONG ELEV TYPE
    La Palma 28.57N 17.83W 2426 Stratovolcanoes
    El Hierro Las Playas 27.73 N 18.03 W 1500 Shield volcano
    Tenerife Las Mesas 28.271 N 16.641 W 3715 Stratovolcano
    Gran Canaria 28.00N 15.58W 1950 Fissure vents
    Fuerteventura 28.35N 14.02W 529 Fissure vents
    Lanzarote 29.03N 13.63W 670 Fissure vents

    It would be La Palma. I read the article, and I'm not exactly sure about those 60 ft waves. I saw a simulation in which the Trade Towers were consumed by the water (and I wasn't watching Day After Tomorrow), with the comment that they made a very mild speculation.

    I'm looking forward to your findings on La Palma .
