Ancient tsunami ‘hit New York’

A huge tsunami may have crashed into the New York City region over 2000 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, said large gravel, marine fossils and other unusual deposits found in sediment cores across the area date to 2,300 years ago.
The size and distribution of material would require a high velocity wave and strong currents to move it, he said, and it is unlikely that short bursts produced in a storm would suffice.
“If we’re wrong, it was one heck of a storm,” said Dr Goodbred.
