Tsumani from Outer Space (6x16)

Air date: Jul 09, 2009

Many scientists, including those at NASA, believe that large meteors plow into the Earth rarely, only every 50 to 100 thousand years. A group of scientists headed by Dr. Ted Bryant believe it's much more often than that. They've found evidence that a huge meteor hit a mere 500 years ago, causing a devastating tsunami that struck Australia. The scientists search coastlines and oceans floors for evidence of previous impacts.
