Asteroid Impact That Killed Dinosaurs Triggered 'Mega

At the end of the Cretaceous, about 66 million years ago, the Chicxulub asteroid impact near the Yucatan peninsula produced a global tsunami ...

It is one of the largest impact structures on Earth, alongside the much older Sudbury and Vredefort impact structures, and the only one whose peak ring is ...

The impact triggered earthquakes with magnitudes over 11; for comparison, the most powerful quake on the human record was 9.5 magnitude in Chile ...

When the 6-mile-wide asteroid that led to dinosaur extinction hit Earth 66 million years ago, the impact also triggered a “mega-earthquake” that lasted weeks ...

The resulting impact, known as the Chicxulub impact after a Mexican town located near the impact site, released a billion times more energy than the atomic bomb ...

It also created several megatsunamis that had waves ranging in size from 100+ m (328+ ft) to 1.5 km (0.93 mi).

Ball and pillow structures; chaotic boulder. - siltstone mixtures;. steeply to vertically inclined sedimentary dykes; structureless or.

New evidence suggests that the Chicxulub impact also triggered an earthquake so massive that it shook the planet for weeks to months after the collision.

A geodynamic change occurred after the 66 Ma Chicxulub asteroid collision. Numerical simulation shows static stress effects up to a distance of hundreds of km.
