Mars: New Discovery – Evidence of a massive tsunami from an asteroid impact 3.4 billion years ago

American and European scientists have announced that they have confirmed previous indications of A Martian The huge tsunami, which may have been caused by the collision of a large asteroid similar to it (Chixulub) with the neighboring planet, whose impact on Earth 65 million years ago led to the extinction of all flightless dinosaurs.

It is estimated that a large asteroid or comet smashed into a shallow ocean in the northern hemisphere of Mars about 3.4 billion years ago. The impact is believed to have created the large 110 km diameter Buhl crater that can be seen today.

Researchers led by Alexis Rodriguez of the Planetary Science Institute in Arizona, who published the appropriate publication in the journal Scientific Reports, They carefully analyzed maps of the surface of Mars Created from satellite images. At the same time, they ran computer simulations of potential impacts to estimate what kind of impact might have created Paul Crater and whether it triggered a massive tsunami.

Thus, they were concluded that they were probably asteroids from three to nine kilometers in diameter, whose fall released up to 13 million megatons of TNT energy. The energy released by the explosion of the most powerful nuclear bomb on Earth (the so-called “Tsar”) was only 57 megatons of TNT.

Scientists appreciate it Such an impact on Mars could indeed cause a huge tsunami of up to 1,500 kilometers from the center of the fall, causing waves up to 250 meters high to land. By comparison, the fall of Chicxulub in present-day Mexico, according to a recent study, may have created a crater 100 kilometers in diameter and triggered a tsunami of up to 200 meters high on the ground.
