Scientists Create Tsunami that Wiped Out Dinosaurs
VIVA – An international group of researchers has used specialized software to reproduce the giant tsunami that is believed to have wiped dinosaurs off the face of the Earth tens of millions of years ago.
Flooding caused by an asteroid caused mile-high waves that have swept across the planet, scientists say. On Monday, the US National Oceanic and Atmospheric Administration (NOAA) posted footage of the computer simulation on Twitter.
The devastating natural event, said to be 30,000 times more powerful than any tsunami on record, was triggered when a large asteroid struck Mexico's Yucatan Peninsula, according to scientists' estimates. The space object is believed to have been more than 10 km (6 miles) in diameter.
The asteroid left a deep mark where it landed in what is now known as the Chicxulub crater. The collision triggered a 4.5 km (2.5 miles) high wave that rippled across the globe, as the new model shows.
The phenomenon also coincided with the Cretaceous-Paleogene extinction that saw 75 percent of all flora and fauna on Earth at the time, including all wingless dinosaurs, wiped out due to massive destruction and subsequent climate change.
The computer simulation is the result of joint work by researchers from several countries, including NOAA's Pacific Marine Environmental Laboratory and Geophysical Fluid Dynamics Lab.
