The Coming Atlantic Mega-Tsunami

timothy posted more than 9 years ago | from the something-will-kill-you dept.

Science 1068

rbrander writes "It's not news at all that scientists predict an eventual "mega-tsunami" that will sweep across the Atlantic that will still be anything from 60 to 150 ft high when it hits the U.S. Eastern seaboard. This Old News, however, suddenly seems fresh. Like an asteroid hit, it could be millenia away, or tomorrow, that a volcano in the Canary Islands just off Africa drops half a trillion tons of rock into the Atlantic. A short description of the problem from BBC News and some more graphic descriptions (of up to 100 million dead) and shrewd commentary on the politics of warning from journalist Gwynne Dyer."

Re:Seems like true (4, Insightful)

jridley (9305) | more than 9 years ago | (#11211770)

RTFA. No, we're not ready, because we choose not to be.

Paraphrasing the article:

A warning would result in the possibility of evacuating tens of millions of people for what could be weeks or months and maybe nothing will happen. Nobody wants to do that.

OTOH, nobody wants to get the warning, not order an evacuation, and be responsible for millions of deaths.

So the "smart" politician's winning game is to not set up the systems where there would be a warning. So there are not enough seismometers to know if there's something about to happen.

Re:Seems like true (1)

WhiplashII (542766) | more than 9 years ago | (#11211775)

It sounds like no one could be ready - the wave would just be too big. All that could be hoped for is an evacuation, and we don't even have early warning systems in place for that.

What really worries me is the possibilities for a terrorist to place a small nuclear bomb there. With a small weapon, placed in a low-security location, a single act of terror could destroy New York, Washington, Boston, etc. - the entire eastern seaboard!

Early warning (1, Insightful)

BWJones (18351) | more than 9 years ago | (#11211589)

At least in the Atlantic, we have an early warning system for Tsunamis and a well developed system of earthquake monitoring that would likely save many lives on the eastern seaboard. All of those expensive homes up on the coast though......

Re:Early warning (4, Informative)

bzebarth (727391) | more than 9 years ago | (#11211621)

I don't think that is true. There are 2 systems in the Pacific but because Tsunamis are very rare in the Atlantic there is no early warning system.

Re:Early warning (0)

Anonymous Coward | more than 9 years ago | (#11211728)

Yes, the news reports recently have reported no detection system in the Atlantic because large quakes and tsunami are rare there.

Re:Early warning (4, Informative)

OECD (639690) | more than 9 years ago | (#11211716)

At least in the Atlantic, we have an early warning system for Tsunamis

Untrue. The Pacific has the only dedicated system (although Tsunamis may be inferred from other equipment like tidal gauges.)

I assume this has been contemplated, but couldn't we cause the threatening hunk of rock to slide in a safer direction? Like cutting down a tottering tree?

Re:Early warning (1)

RealityMogul (663835) | more than 9 years ago | (#11211777)

It's a significant land mass, it's not a tree. If we had the power to move it, we could just as easily hold it in place.

Not without destroying most of the Island, plus where talking about a lot of rock here, This is more than just removing the top of some mountain ( which is hard enough ), I think you'd have to go down quite a way to the sea floor. Where talking trillions of tons of rock off an active volcano, which might even distrub it enough to set it off anyway.

How you would do it, who would pay for it, and would the locals let you? are also some of the other considerations.

Re:Early warning (5, Insightful)

timcrews (763629) | more than 9 years ago | (#11211748)

How do you suppose two or three hours of warning would help in the task of evacuating 50 to 100 million people? Take, for example, the recent rash of hurricanes in the southeast U.S. Even with days of notice, the interstate highways out of Florida resembled parking lots.

It seems to me, as with the asteroid collision possibility, that the better (only?) approach is prevention. Perhaps it would be worthwhile to investigate the possibility of gradually, and very, very carefully, relieving the stress on this cracked volcano, so that a 90-second catastrophic slide is replaced with a sustained slow erosion of the material.

There would still be a difficult political situation. It is entirely possible that the stress relief effort would carry its own risks of _causing_ the catastrophe it was designed to prevent. Similar tradeoffs occur in almost any risk mitigation strategy, although seldom with the stakes being this high.

Where are you going to go? If you're talking U.S., there's potential for bad things to happen no matter where you are. F5 tornadoes...hurricanes...Mt. St. Helens.
Then there's overseas, where unexpected things happen as well, such as this tsunami or sand storms in the Middle East. There's no reason to simply leave...the fact is that you'll die when it's your time. Period. Whether it's by a natural disaster, or cancer, or a car accident.

Because everyone decided to not worry about an Indian Ocean tsunami. "It's unlikely to happen anywhere other than the Pacific Ring of Fire" they said.

Now we do the intelligent thing, which is learn from past mistakes. With a watch system like the one for the Pacific, we can mitigate the disaster.

Wouldn't we all feel real stupid if we decided to do nothing and an Atlantic tsunami hit?

Wikipedia (4, Informative)

Andorion (526481) | more than 9 years ago | (#11211595)

Here's the Wiki link for a Megatsunami [wikipedia.org] . Here's an excerpt:

"During an eruption that is anticipated to occur sometime within the next few thousand years the western half of the island, weighing perhaps 500 billion tonnes, will catastrophically slide into the ocean. This will inevitably generate a megatsunami which will travel across the Atlantic and strike the Caribbean and the Eastern American seaboard several hours later with a wave possibly 90 meters (300 feet) high, resulting in massive coastal devastation.

Re:Wikipedia (5, Interesting)

Altus (1034) | more than 9 years ago | (#11211719)



one has to wonder if we could defuse the problem by putting that mass in the water now, in a controlled manner. couldnt we start blowing off chunks of the island now and minimize the impact of any possible eruption?

clearly you would have to be very careful and the cost would be very high, but if everyone is certain that this mega tsunami is going to happen wouldnt it make sense to spend the money up front rather than on disaster relief?

that's a great thought...but, i have a question...even in a controlled manner, isn't dumping 500 billions tons worth of land mass gonna into the ocean gonna cause some water levels somewhere to rise? sure, it won't be all at once in a 300 ft wave (which would be pretty cool), but i'm guessing you'd still be flooding a lot of land...

Re:Wikipedia (1)

nbert (785663) | more than 9 years ago | (#11211814)

Well if it's such a big deal why don't we at least consider to ablate the parts which could possibly fall of?

Might sound naive and there might be the risk of triggering the landslip during the process, but wouldn't it be an option? I guess the people living on La Palma wouldn't be happy about it, but if so much is at stake...
(and yes, I've been there so I know that we are talking about moving some rocks)

On a side note there is a giant crack about 2 meters wide and deep going through half of the island. I can't really remember any details, but it was caused by an earthquake and might be a leading sign.

circletimessquare (444983) | more than 9 years ago | (#11211760)

you CAN do something about the canary island threat: shave the mountain away, bit by bit

the canary island threat is an above-water threat of fixed location, unlike the undersea, underearth, unseen, unlocated threat in the indian ocean, or the more usual suspects in the pacific ring of fire

it would be an enormous task, and cost billions, but after the deadly tsunami in asia, you can bet there might be some real interest in the possibility now

your fatalism makes sense about candy wrappers and death at age 95, but even you would go out of the way to not step on a candy wrapper, if you SAW IT at the top of the stairs, no?

well guess what: we see the canary islands, we don't have to fall down those stairs

therefore, your fatalism is an inappropriate response to the canary islands possibility

Chimichanga (-1, Troll)

Anonymous Coward | more than 9 years ago | (#11211597)

Lets make chimichangas instead of worrying about this!

1/4 c. bacon grease
2 c. chopped or shredded cooked chicken
1 med. onion, diced
2 cloves garlic, minced
2 med. tomatoes, chopped
2 cans (4 oz.) chopped green chilies
1 lg. peeled, boiled potato, diced
1 tsp. salt
1 1/2 tsp. oregano
1 to 2 tsp. chili powder
2 tbsp. minced, fresh cilantro
12 lg. flour tortillas, warmed
Vegetable oil
Shredded cheddar
Sour cream
Guacamole
Salsa
Shredded lettuce, chopped tomatoes, sliced black olives

In skillet, melt bacon grease over medium heat. Saute meat, onion, garlic, tomatoes, chilies and potatoes; until onion softens. Add salt, oregano, chili powder and cilantro; simmer 2 to 3 minutes.

Place 1/2 cup meat filling on each tortilla. Fold envelope style (like a burrito). Fry, seam side down, in 1/2 inch of hot oil, until crispy and brown. Turn and brown other side. Drain briefly on paper towels.

Place on plate and top with shredded cheese, sour cream, guacamole and salsa. Place shredded lettuce around chimichanga and top lettuce with chopped tomatoes and sliced black olives. 12 servings.

Can substitute cooked beef or pork for chicken.

When governments are faced with the first kind, they can respond quite sensibly.

Some bad science in the post (5, Informative)

Chairboy (88841) | more than 9 years ago | (#11211630)

There's some bad science in the post, especially the comment about the wave being 'still' that high. Most tsunamis are very small out in the ocean, most less then a few centimeters tall.

They don't get big until they approach the shore and the depth gets shallow.

The small waves, btw, travel around the speed of a jetliner, hence the lack of warning.

i41Overlord (829913) | more than 9 years ago | (#11211724)

It seems that nowadays the news has become entertainment instead of information. Journalists scurry to find ways to make The Next Big Headline (tm). Instead of finding ways to make people feel better or do something to help those that need it, they try to find ways to surprise and upset people- anything that will make people watch their channel or read their newspaper.

Now in the wake of a real natural disaster, all the journalists are hopping on the "tsunami disaster" bandwagon. They're thinking "how can I apply the fear from the disaster which just took place on the other side of the Earth to my own hometown? I bet that'll sell a lot of papers!"

Summary- there seems to be a big market for profiting from fear and doom 'n gloom predictions and not a very big market for helping people.

This would be the greatest weapon ever. (4, Interesting)

scorp1us (235526) | more than 9 years ago | (#11211729)

Imagine a terrorist organization that detonates a bomb in the fissure. It is the stuff movies are made about. (Indecentlally if you are a movie maker you can buy that idea off me) You'd nail every country you hate and then some. But the problem is it only works once, so it is not good for terrorism per se.

The solution is the same as the problem. I would fracture the land mass and incrementally slide it in to the ocean. Several planned tsunamis are better than one big unplanned one.

I do not know if it is possible, but with that death toll and desvistation, it looks like we should get some geologists down there to see if it can't be done. It is resy though, you don't want to trigger the whole thing. Perhaps, it could be divided horizontally to remove the downward stress, rather than splitting slices off vertically?

You might want to read 'State of fear', especially if you're a 'global waming' sceptic (Michael Crichton would appear to be...)

It's not news at all that...

So why is it being posted on a news website? I realise this has been brought to attention by recent events, but does it really need front page posting?

Saw this on Drudge 2 days ago (1)

When will Slashdot have some News, instead of being just an RSS aggregator with commentary?

Isn't there a way to blow up that island in advance, so that the tsunami will be entirely predicted and planned? Like, put some explosives at several strategic places, and blow them up one at a time to divide the mega tsunami into many mini tsunamis.

It might be a REALLY long and REALLY expensive process, but the costs would be less than the casualties and enormous economical damages a tsunami would cause. How about using all those bombs for something useful, instead of dumping them on Iraqis?

Weaponized Tsunamis? (1)

So how long before the US government or Osama figures out that a nuclear bomb or (maybe) even a good chunk of high explosives trigering a landslide can be used as a weapon of mass destruction... a delivery system if you will?

Whoops. Quick delete this post before Osama reads it. Nah, his folks are just as smart as me.

You don't have to get close to the US with your big bomb... just send the wave across the sea. However I suspect that the power unleashed by a 9.0 magnitude earthquake is much larger than any inexpensive nuclear device they could lay their hands on.... but if a nuclear device could trigger a huge landslide.... well then.

Well.

Very interesting.

I feel pretty safe in Portland Oregon, possible erruptions of Mt. St. Helens and Mt. Hood aside.

But coastal Oregon and the Pacific region? The Atlantic seaboard?

Yikes.

Wave Height (5, Informative)

bzebarth (727391) | more than 9 years ago | (#11211769)

that will sweep across the Atlantic that will still be anything from 60 to 150 ft high when it hits the U.S. Eastern seaboard

I heard an interview with someone from NOAA with the Pacific Marine Environmental Laboratory in Seatle that described what happens when a Tsunami occurs. He said when the wave travels through deep water it has tremendous speed (hundreds of mile/hour) but is only a few feet high. As it comes into shallow water the wave slows down to 10s of miles/hour and that causes the huge wall of water. So a Tsunami is not really a 100 ft wave as it travels through the ocean only once it nears land.

Just my $.02.

Tsunami Tsimulator? (3, Interesting)

starglider29a (719559) | more than 9 years ago | (#11211778)

In the same vein as the Asteroid Simulator page (http://www.lpl.arizona.edu/impacteffects/), is there anything that can give us some ballpark figures on tsunami wave height and speed vs. distance for a given energy? (Like an Asteroid Strike?) Using 2004 MN4 as a sample, The Impact Simulator gives this value. "The crater opened in the water has a diameter of 5.41 km = 3.36 miles"

Can we use that to estimate a wave height at a given distance?

Also, if an impact we in the Indian Ocean, what effect would be seen in the Red Sea and the Persian Gulf, being narrow, shallow waterways? We all remember the "shotgun blast" from the Gulf of California in Lucifer's Hammer, now don't we?

FREAK OUT!!!!! I think we have finally found the #1 terrorist. It is Mother Nature and she is one bad bitch.

Easy solution (1)

jsrlepage (696948) | more than 9 years ago | (#11211793)

You just send ballistic missiles confront the waves, and the moment they get to the tidal wave, make em explode and break the wave. seems simple enough to work.

AND you get to disarm whatever country's smart enough to care more about the lives of the citizens than the sparkle of their missiles.

Maybe this is a really stupid question (1)

AndyboyH (837116) | more than 9 years ago | (#11211797)

but if they're that worried about this, why not simply remove the volume of water surrounding the area by either creating an artificial island, or creating a group of enough aquatic piles and removing the seawater to such an extent that it wouldn't matter, or would severely reduce the height of the waves?

I know half a trillion tons of rock is a lot, but then so are a hundred million lives.

[goes into politics]

It would also divert money away from the US's more aggressive home defence foreign policies, which can't be a bad thing...

And if you want to keep a scary 'terror' paranoid perspective - I wonder what kind of airliner or ship would be required to give that mass of earth the correct nudge to cause a catastrophic mega-tsunami?
