The asteroid that pummeled Earth 66 million years ago transformed life on this watery planet, decimating the dinosaurs and bringing on a new era in biology.
The asteroid also created a monstrous tsunami thousands of times bigger than any wave ever witnessed in humanity's blip of existence, according to new research.outer reaches of the Solar SystemThe splashdown alone was powerful enough to leave a signature into the face of the planet.
The team modeled the first 10 minutes after impact and the subsequent ripple effects through the world's oceans in what is the first global simulation of the tsunami raised by the Chicxulub asteroid. Refining simulations first presented at an earth science conference in 2018, modeling showed the asteroid generated waves up to 30,000 times more energetic than theThe initial blast from the Chicxulub impact displaced so much water it generated a wave roughly 1.5 kilometers high. All of that space didn't remain empty for long, with the ocean gushing back in to fill the gaping crater, only to ricochet off its rim and create yet more waves.
From there, tsunami waves over 10 meters tall traveled through the deep ocean at 1 meter per second to lash at coastlines around the world. "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,"
