Asteroid that killed the dinosaurs also triggered global tsunami

The asteroid that struck Earth 66 million years ago, wiping out three-quarters of the planet’s plant and animal life (most famously the dinosaurs), also triggered a worldwide tsunami with mile-high waves.

A new study led by University of Michigan scientists reveals that this tsunami scoured the ocean floor and left geologic traces as far away as New Zealand — thousands of miles away from the impact site off what’s now Mexico’s Yucatan Peninsula. The findings come from the first simulation that models the global effects of the impact of the massive asteroid — named the Chicxulub impactor — upon Earth to reach publication.
