Did a big wave hit the Big Apple way back when? Scientists say a tsunami struck the New York City area 2,300 years ago, possibly as a result of a meteorite crashing into the Atlantic Ocean.
“It would have been a bad day to end all bad days,” research scientist Dallas Abbott of Columbia University's Lamont-Doherty Earth Observatory tells today's New York Times.
While no one has found a large crater that would indicate that a meteorite struck, Abbott discovered miniscule diamonds and tiny carbon spheres in Hudson River sediment that may be signs that a rock 330 feet (100 meters) across hit the New York City area. Abbott and colleagues at Harvard University reported their finding earlier this month at the American Geophysical Union meeting in San Francisco.
Scientists working on Long Island and the New Jersey shore previously found thick deposits of sediment that may indicate a tsunami hit the area. Still, there's no archeological evidence of a tsunami there, and the new suggestion of a meteorite impact in the Atlantic isn’t enough to convince all other scientists that a big wave occurred.
"To get a wave 2.5 meters high that far up the Hudson, you need a wave 20 meters high at Manhattan," Steven Ward, a research geophysicist at the University of California, Santa Cruz, told Discovery News. "It would've gone several hundred meters inland on Long Island; you should see evidence of this thing all over the place."
This isn’t the first time scientists have challenged the conventional wisdom that natural hazards don't happen in the Big Apple. A Columbia University study in August suggested there's more seismic activity around New York than originally believed, though the chance of an earthquake striking the city is still unlikely.
JAKARTA, Indonesia (AP) - A series of powerful earthquakes shook remote eastern Indonesia on Sunday, toppling or badly damaging more than 100 buildings and leaving at least four people dead and dozens injured.

New theory suggests a colossal reaction spewed out the Moon's material
Not long ago, when humans visited the Moon, there were still many theories related to the way it formed, but soon they were ruled out, one by one. For instance, one stated that it formed, like the Earth, from the accretion of space dust into increasingly larger lumps, another stated that it was born in a different region of space and captured later by our planet, a third envisioned a young Earth rotating so fast that the centrifugal force detached the Moon's matter from our planet.
As for the last, not even the calculated rotation velocity that caused a terrestrial day to be only 2.5 hour long could cause matter to be displaced, "The centrifugal force was insufficient for a Moon to escape," shared retired Dutch nuclear geophysicist Rob de Meijer. More recently, the proposal of the Moon forming from the debris resulting in the Earth's ancient massive impact with a cosmic body was largely adopted.
But de Meijer and van Westrenen propose a new possibility, that a georeactor very close to the young core, more precisely in the D'' layer (the thin, dark orange layer that can be seen in the adjacent picture) suddenly went supercritical. A powerful chemical reaction vaporized the rock, and the generated bubble rising through the molten mantle and the crust provoked an immense eruption of some trillion tons of material that gave birth to the Moon.
"The material in the Earth's mantle heated up some 8,000ºC and was completely vaporised. This huge bubble of gas forced itself up through the still liquid mantle," explains de Meijer. "As a result, part of the Earth's mantle and crust were blown away, as well as the early atmosphere. From the debris, the Moon could have formed rather quickly." Their hypothesis will be assessed and, most likely, vividly contradicted in the months to come.
