Ancient Tsunami 'Hit New York'

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. The scenario, proposed by scientists, is undergoing further examination to verify radiocarbon dates and to rule out other causes of the upheaval. Sedimentary deposits from more than 20 cores in New York and New Jersey indicate that some sort of violent force swept the Northeast coastal region in 300BC. It may have been a large storm, but evidence is increasingly pointing to a rare Atlantic Ocean tsunami. Steven Goodbred, an Earth scientist at Vanderbilt University, said large gravel, marine fossils and other unusual deposits found in sediment cores across the area date to 2,300 years ago. He also said "If we're wrong, it was one heck of a storm’’.
