BUT megatsunami The Martian could have been caused by the impact asteroid similar to that which results from chicxulubwhich wiped out the dinosaurs on Earth 66 million years ago.
Research published in the journal ‘Scientific reports‘ describes a huge impact crater in the northern lowlands Mars in the area where the ocean was Mars ancient.
New information
Previous studies have suggested that the impact asteroid or a kite in the low-lying ocean north of Mars this may have caused a megatsunami approximately 3.4 billion years ago. However, prior to this study, the location of the resulting impact crater was unclear.
Alexis Rodriguez and his colleagues from the Institute of Planetary Sciences in Tucson (USA) analyzed surface maps Marscreated by combining images from previous missions to the planet, and identified an impact crater that could have caused the explosion. megatsunami.
The crater, which they named Pol, is 110 kilometers in diameter and is located in an area of the northern lowlands, which, according to previous studies, could be covered by the ocean, in an area located about 120 meters higher. sea level is below the estimated sea level. The authors suggest that Paul may have formed about 3.4 billion years ago, based on its position above and below rocks previously dated to that time.
The authors simulated asteroid and comet collisions with this region to see what kind of impact Paul could create and whether it could cause a catastrophe. megatsunami. They found that simulations that formed craters with dimensions similar to Paul’s were caused by asteroid nine kilometers, which met with strong resistance on the ground, releasing 13 million megatons of TNT energy, or asteroid of three kilometers that met with little resistance in the ground, releasing 0.5 million megatons of energy in TNT equivalent.
The amount of energy released by the Soviet tsar, the most powerful nuclear bomb ever tested, amounted to approximately 57 megatons of TNT energy.
Both simulated impacts produced craters 110 kilometers in diameter and generated megatsunami which reached 1500 kilometers from the center of the impact site. Analysis megatsunami caused by a three-kilometer asteroid impact showed that this tsunami could have a height of up to about 250 meters on land.
The authors speculate that the aftermath of Paul’s alleged hit may have resembled that of chicxulub on Earth, which, according to previous studies, occurred in an area 200 meters below sea level, formed a crater with a temporary diameter of 100 kilometers and caused megatsunami 200 meters above the ground.
