'Any historically documented tsunamis pale in comparison with such global impact.'
Just off of the western coast of Mexico’s Yucatán peninsula lies the 12 mile deep, 6.2 mile wide. The 66 million year-old impact crater is the site where a massive asteroid struck the Earth, wiping out the dinosaurs and about three quarters of all life on Earth. But new evidence shows that it was even more destructive than previously realized.
“This tsunami was strong enough to disturb and erode sediments in ocean basins halfway around the globe, leaving either a gap in the sedimentary records or a jumble of older sediments,” lead author Molly Range, who conducted the modeling study for a master’s thesis at the University of Michigan, saidIf that asteroid had been 30 seconds late, dinosaurs might rule the world and humans probably wouldn’t exist.
To determine just how powerful the tsunami was, the team analyzed the published records of 165 marine boundary sections, or marine sediments in the geologic record deposited around the time the asteroid struck the earth, and sediment cores. The cores act as a terrestrial timeline that scientists can use to analyze the layers or rock, sand, and ice to better understand what the Earth was like millions of years ago.
