First global tsunami simulation of the Chicxulub Asteroid Impact 66 million years ago


The 6+ miles-wide asteroid that struck Earth 66 million years ago wiping out nearly all the dinosaurs and roughly three-quarters of the planet’s plant and animal species also triggered a megatsunami with mile-high waves that new research confirms its global impact.
