What if a Huge Asteroid Hits the Atlantic?
By JOHN NOBLE WILFORD


WASHINGTON -- If a huge asteroid crashes into the middle of the Atlantic Ocean, say goodbye to Broadway, the beach house on Long Island and just about everything else on the East Coast as far inland as the foothills of the Appalachians.

The coastal lands would be devastated not by the actual impact, some 1,500 miles away, but by a relentless succession of tidal waves traveling at the speed of jet aircraft and towering much higher than the Empire State Building.

In the aftermath, a few hours later, the receding waters would leave almost nothing standing.

Though this may sound like the story line for Hollywood's next disaster movie, such a projected catastrophe has been churned out by computers at Los Alamos National Laboratory, a place in New Mexico that would remain high and dry. Scientists described the results of the computer simulations here Wednesday at a meeting of the American Astronomical Society.

Dr. Jack G. Hills, a Los Alamos geophysicist, said the tidal wave, or tsunami, generated by the asteroid's impact would be far more devastating than any earthquake, volcano or previously known flood in human history.

Coastlines in Europe would also be wiped out, particularly in Ireland, France, Portugal and Spain.

The simulations were conducted as part of studies at Los Alamos on the problems of detecting nearby asteroids that could endanger Earth and possibly knocking them off course with a nuclear missile. The laboratory was founded to develop nuclear weapons, but no such use of them for asteroid-defense has been authorized.

For the computer simulations, Hills, working with Dr. Charles Mader, a retired Los Alamos scientist and specialist in tsunamis, created models showing how impacts by asteroids of different sizes would generate tidal waves that, from previous experience, gain power as they reach offshore continental shelves. Models of coastal topography were included to show how far inland flooding was likely to occur.

The worst-cast simulation assumed the impact of a rocky asteroid three miles in diameter. It would lose little energy plunging through the atmosphere and would gouge out a crater on the Atlantic floor.

An asteroid about twice that size slammed into the Gulf of Mexico and Yucatan 65 million years ago, presumably causing global extinctions.

Within three hours, the simulations showed, tidal waves would deliver walls of water and a crash of debris to the East Coast, from New England through the Carolinas. The more gentle continental shelf off Florida should temper the effects on that state's coastline, except in the Miami area, which would be devastated.

Fortunately, asteroid impacts of that magnitude occur on an average only once every 10 million years. But the chance of a relatively small asteroid hitting the ocean is 2,000 or 3,000 times more likely. One that is 1,300 feet wide would wipe out the coasts on both sides of the Atlantic with a tsunami more than 300 feet high.

"Any asteroid over 600 feet in diameter, we have a real problem," Hills said.

The laboratory has begun comparable simulations of the effects of an asteroid in the Pacific on Hawaii and the West Coast.

The entire Los Angeles basin would be swamped.

"Our colleagues at Caltech in Pasadena might make it," Hills said, "but UCLA, no."

Tsunamis are usually caused by underwater earthquakes or volcanic eruptions. One of the worst on record began off the coast of Chile and produced waves of up to 15 feet as far away as Japan.

At 8 p.m. on June 5th, 8498 BC, the core parts of Asteroid A punched the first decisive hole in the fracture zone of the Atlantic Ridge. The forces of hell were let loose. Thorough these two newly formed vents the glowing red-hot magma shot up at terrific speed and mixed with the liquid above it - the waters of the Atlantic. This created all the conditions for a submarine volcanic eruption of the greatest possible violence. The fracture seam was torn apart. The bottom of the sea burst open. All existing volcanoes were activated and new vents formed. Terrestrial fire and ocean water became embroiled in ever-increasing volume. Magma mixed with steam. The chain of fire ran all the way between the two continents from the Beerenberg volcano on Jan Mayen in the north to Tristan de Cunha in the south.

This rather dramatic description from the back of Otto Muck's book - The Secret of Atlantis - is based on his ideas about the causal relationship between isotherms and favorable climate in northwestern Europe, and the unobstructed flow of the Gulf Stream across the Atlantic. Muck tries to use this flow to make a case for the prior existence of a large body of land in the Atlantic whose subsidence changed the ocean currents and warmed the British Isles about 10,500 years ago, give or take a day or two. Based on a varied and interesting collection of hard data, Muck suggests that the submarine massif of the Azores was once above water and could have blocked and deflected the Gulf Stream, preventing the circulation of the warmer waters, and thus contributing to the freezing temperatures of the British Isles.

There are other solutions to the problem of the isotherms including current day research showing that this can result from global warming. While we don't deny that it's possible for such severe lithosphere disruption as Muck suggests to occur, and we aren't playing soft with the idea of mass destruction of species, it just seems that an event that would produce the sinking of so vast a body of land so completely would be an event from which absolutely nothing on the earth would survive.

Nevertheless, Otto Muck draws our attention to the meteor craters in the Carolinas. The Carolina bays are mysterious land features often filled with bay trees and other wetland vegetation. Because of their oval shape and consistent orientation, they are considered by some authorities to be the result of a vast meteor shower that occurred approximately 12,000 years ago. What is most astonishing is the number of them. There are over 500,000 of these shallow basins dotting the coastal plain from Georgia to Delaware. That is a frightening figure.

Let me repeat: there are over 500,000 of these shallow basins.

Unlike virtually any other bodies of water or changes in elevation, these topographical features follow a reliable and unmistakable pattern. Carolina Bays are circular, typically stretched, elliptical depressions in the ground, oriented along their long axis from the Northwest to the Southeast. [T]hey are further characterized by an elevated rim of fine sand surrounding the perimeter. []

Robert Kobres, an independent researcher in Athens, Georgia, has studied Carolina Bays for nearly 20 years in conjunction with his larger interest in impact threats from space. His recent, self-published, investigations have profound consequences for Carolina Bay study and demand research by academia as serious, relevant and previously unexamined new information. The essence of Kobres' theory is that the search for "debris," and the comparison of Bays with "traditional" impact craters, falsely and naively assumes that circular craters with extraterrestrial material in them are the only terrestrial evidence of past encounters with objects entering earth's atmosphere.

Well I guess this rules out other things like gamma bursts and fragmenting comets.
Although, where is this record of ejecta in the geologic record?

I don't mean to be a party crasher, but on several other times we had very near Earth objects go sailing past we were told about it on the news the next day.

BOOM! We will take the strike and end up with another near exstiction event.
The closest we've even come to shooting one down was an impactor sent to a local comet to find out what it's made of. It made a nice short lived show of ejecta and it kept on going.

MIT computers should be running models based on current trajectories of atleast the known objects around us.

Yeah but then they would be helping us more by telling us how to do it ourselves.

We'd still have a hard time shooting down an asteroid.

We did shoot a big spy satellite out of the sky a few months ago, though, anyone remember that?  So, we are getting better at it!

This power came forth out of the Atlantic Ocean. But afterwards there occurred violent earthquakes and floods; and in a single day and night of misfortune all your warlike men in a body sank into the earth, and the island of Atlantis in like manner disappeared in the depths of the sea.
