Tsunami from dinosaur-killing asteroid had mile-high waves and reached halfway across the world

The dinosaur-killing asteroid that slammed into Earth 66 million years ago also triggered a jumbo-size tsunami with mile-high waves in the Gulf of Mexico whose waters traveled halfway around the world, a new study finds.

Researchers discovered evidence of this monumental tsunami after analyzing cores from more than 100 sites worldwide and creating digital models of the monstrous waves after the asteroid’s impact in Mexico’s Yucatán Peninsula.
