In May 2018, the highest wave recorded in the southern hemisphere in modern history was recorded on the islands of Campbell.
Criterion is 23.8 meters. Can you imagine a wave that measured almost 70 times more?
65 million years ago, a 14-kilometer asteroid hit the Earth with catastrophic consequences.
It caused the shock a crater with a diameter of 180 km, the center of which lies on the current Yucatan Peninsula, Mexico.
Baptized the angle Asteroid Chicxulub, the object could be part of a much larger asteroid, which was divided into several fragments after the impact in space.
Among other things, I could be the reason for this the extinction of dinosaurs, that over 135 million years ago, land vertebrates prevailed.
Now a team of researchers from the Department of Earth and Environmental Science at the University of Michigan in the United States ensures that the asteroid is also formed. a tsunami which caused an unimaginable destruction.
According to the group of scientists, the huge impact caused the asteroid to slip 1500 meters deep in ten minutes after the accident.
Its speed was such that all the water that it was towed went to the bottom of the ocean, so that the crater was empty at that moment.
The force of the water in returning to the surface was caused by a tsunami that he had never seen before.
It is estimated that he had the power 29,000 times higher an earthquake and a subsequent tsunami in the Indian Ocean, which killed more than 200,000 people in 2004.
By simulation, scientists found that the impact of the Chicxulub asteroid caused a wave of 1,600 meters in height.
Or, which is equal, more than 4 times the height Empire State Building from New York.
In the first meters, the tsunami reached a speed higher than 140 kilometers per houraccording to scientists.
This gigantic initial wave has been created by hundreds replica the smaller ones, who traveled at great speed for a good part of the planet.
In the first 24 hours, the effect of the tsunami spread from the Gulf of Mexico to the Atlantic.
"Asteroid Chicxulub has caused great tsunami, as it has not been observed in modern history," said Molly Range, the lead researcher of the project, Live Science
He added: "I only met the true extent of the tsunami at the very beginning of this project."
Without a doubt, before and after for our planet.
