Tsunami sur New York

Selon de récentes découvertes scientifiques, la chute d'une météorite dans l'Atlantique aurait provoqué un énorme tsunami sur la région de New York.

Extraits de l'article:

A meteorite impact off Long Island 2,300 years ago may have set off a huge tsunami that flooded the New York City region, a new study says (...) The evidence included deformed rocks; rare microscopic "nanodiamonds"; and microscopic, perfectly round rocks called spherules, which form when molten and vaporized rock are flung into the air by a space impact and then solidify in the temporary vacuum created by the blast. Nothing as big as a crater has been found, but Dallas Abbott, a Columbia University impact expert, estimates that the space rock would have had a diameter of between about 165 feet (50 meters) and 490 feet (150 meters). Any smaller, and a major wave would not have formed and the rock would have exploded before hitting Earth. Any bigger, and the strike would have created "impact glass"—forged in the extreme heat of an impact blast—which has not been found as of yet.
