Tsunami Hit New York City Region In 300 BC

Hugh Pickens writes "Scientists say that sedimentary deposits from more than 20 cores in New York and New Jersey indicate a huge wave crashed into the New York City region 2,300 years ago, dumping sediment and shells across Long Island and New Jersey and casting wood debris far up the Hudson River. Steven Goodbred, an Earth scientist at Vanderbilt University, says that size and distribution of material would require a high velocity wave and strong currents to move it, and it is unlikely that short bursts produced in a storm would suffice. 'If we're wrong, it was one heck of a storm,' says Goodbred. An Atlantic tsunami is rare but not inconceivable, says Neal Driscoll, a geologist from Scripps Institution of Oceanography, who is not associated with the research. The 1929 Grand Banks tsunami in Newfoundland killed more than two dozen people and snapped many transatlantic cables, and was set in motion by a submarine landslide set off by an earthquake."

    A few years ago I had a relative who was involved in a lot of the disaster planning for New Haven. Some scenarios were so bad that he more or less concluded that there wasn't any point in trying to make any substantial preparations because there wouldn't be anything they could do that would help. A large tsunami hitting New England was one of the situations. Either you get a warning on time or you don't. Not much local governments can do about it.

      Umm, sorry you got the math wrong.

      It is the tsunami WAVE that travels at 1000km/h. There is no way the water itself travels at that speed. (It is almost the speed of sound. Do you really believe tsunami waves cause ocean to fly hypersonic?)

      Think of the sound: it travels at 340m/s, which does NOT mean that the medium (air) travels at that speed.

      The correct way to estimate tsunami's energy, I believe, is to calculate its *potential* energy. I.e., (200km*pi*1m^2)*1000kg/m^3 * 9.8m/s^2 * (roughly) 0.5m = 3*10^9 J.

      Multiply by 2, because waves tend to have 50:50 mix of potential & kinetic energy, if my memory of classical mechanics is correct.

    The great flood must have been somewhere else. There weren't that many Jews living on Long Island back then. But poor New Jersey.. Even mother nature was dumping its garbage there.

    You're talking about La Palma.

    And yea, no one is really sure what will happen when it goes into the sea. It depends a great deal on how it goes, I suppose.

    My money is on Yellowstone violently erupting, which shakes apart La Palma.

    Second virtually every culture in the world has a record of a flood circa 8000 BC, from the Jews to the Eqyptians the Iraqis, Indians, and Chinese.

    citation please? some cultures have flood myths but where did you get the idea that they all pin the date down to circa 8000BC? and how circa is circa? Indeed the dates seem to be all over the place. They also seem to involve their cultures surviving the flood, which isn't much use to people trying to prop up the Genesis flood story. Unless noah's family traveled the globe restablishing exact replicas all the cultures of the world and then carried on as if nothing had happened. Presumably noah had at least one black kid, and one asian kid, etc.

    Your analogy is REALLY flawed. Being Black doesn't imply a certain rational framework, or adherence to a certain theory. As far as I know, no ethnicity has a defining body of theory, that once they change their minds, they change their race.

    I just stopped believing that the Earth Revolves around the Sun, therefor I ceased to be white.

    Your statement is rather silly, since basically your saying that no group that holds a view contrary to science, reason, or evidence, should be discredited, even if this opens a very large can of worms, since there are so many contradictory views. This is especially true when you make a statement of an ontic nature, which is falsifiable such as the claims of the young earthers. Either the world is 3000 years old, or it isn't, and proof would exist that would prove or disprove one or the other claim. Faith never plays into it.

    Intolerance would be saying "never tolerate religious group x", which is almost as bad as racism, even if it is much more prevalent than racism. Though oddly religious groups seem much less tolerant than anyone else, since your are a bad bad person if you don't align with their sexual, social, or ideological mores.

    I have nothing against religion, or the religious as long as they don't try to muck with my life, or tell me what do based on what their supreme deity of choice told them, since that argument has no bearing on my life. If they keep their ideas away from me, I'll happily ignore them. UNTIL, that is, they try to pass of faith for reason because of religious arguments. The second they say something disprovable, it is fair game, and they shouldn't complain when someone attacks it with evidence, science, and reason.

    I cannot scientifically disprove God or gods, but I can easily disprove the world being 3000 years old, or similar claims.

    There is no right to be wrong, especially when you try to spread falsehood as unassailable truth (there is no such thing as an unassailable truth, truth should be attacked at every chance we have, just to make sure truth is REALLY truth, and some some pleasing falsehood that makes us happy).

    I grew up 5 miles from the water on Central Long Island's "South Shore". When I was a kid my friends father had a large garden, about 80 yards by 20 yards. Every year when he would till/turn the soil, large crumbling shells would turn up. We always wondered why they were so close to the surface in a place that had been above sea level for millions of years. Maybe this is the answer.
