‘Dinosaur-Killer’ Asteroid Strike On Mars Caused A Mega-Tsunami 3.4 Billion Years Ago, Say Scientists

An enormous tsunami might have surged by way of an historic ocean on Mars after an asteroid collision just like the one which killed the dinosaurs on Earth 66 million years in the past, in response to a brand new paper printed at this time.

The work in Scientific Stories reveals a crater 68 miles/110 kilometers huge within the purple planet’s northern lowlands that earlier research have advised might have been lined by an ocean.

Planetary scientists see proof of water throughout Mars and a few theorize that the purple planet was as soon as a blue planet like Earth.

Nicknamed, Pohl, it’s thought that the crater may have been been the results of Mars being struck by an unlimited asteroid just like the Chicxulub asteroid that’s thought to have contributed to the mass extinction of all non-avian dinosaurs on Earth 66 million years in the past.

Based mostly on its place above and under rocks beforehand dated the authors counsel that the Phol crater might have fashioned round 3.4 billion years in the past. At the moment the area is assumed to have been underneath about 400 ft/120 meters of water so would have triggered what the authors name a “megatsunami.”

It was already suspected that an asteroid or comet had struck an ocean within the Martian northern lowlands, however that is the primary time a crater has been recognized.

Simulations by the scientists counsel that craters with related dimensions to Pohl have been brought on by both:

  • a 5.6 miles/9 kilometre-wide asteroid encountering robust floor resistance – releasing 13 million megatons of TNT vitality .
  • a 1.9 miles/three kilometre-wide asteroid encountering weak floor resistance – releasing 0.5 million megatons of TNT vitality.

Probably the most highly effective nuclear bomb ever examined, be aware the authors, launched 57 megatons of TNT vitality.

The simulations revealed that the ensuing megatsunami may have been round 820 ft/250 meters tall and reached so far as 932 miles/1,500 kilometres from the crater.

That’s all similar to what occurred through the Chicxulub affect on Earth.

Wishing you clear skies and huge eyes.
