Mars Megatsunami May Have Been Caused by Chicxulub-Like Asteroid Impact A Martian megatsunami may have been caused by an asteroid collision similar to the Chicxulub impact – which contributed to the mass extinction of all non-avian dinosaurs on Earth 66 million years ago – in a shallow ocean region
An asteroid collision may have caused a Martian megatsunami approximately 3.4 billion years ago. New research has identified an impact crater that could have resulted from the asteroid impact that caused the megatsunami.A Martian megatsunami may have been caused by an asteroid collision similar to the Chicxulub impact – which contributed to the mass extinction of all non-avian dinosaurs on Earth 66 million years ago – in a shallow ocean region.
The authors simulated asteroid and comet collisions with this region to test what type of impact that could have created Pohl and whether this could have led to a megatsunami. They found that the simulations that formed craters with similar dimensions to Pohl were caused by either a nine-kilometer asteroid encountering strong ground resistance – releasing 13 million megatons of TNT energy – or a three-kilometer asteroid encountering weak ground resistance – releasing 0.
Both simulated impacts formed craters measuring 70 miles in diameter and generated megatsunamis that reached as far as 900 miles from the center of the impact site. Analysis of the megatsunami caused by the two-mile asteroid impact indicated that this tsunami may have measured up to approximately 820 feet tall on land.
The authors suggest that the aftermath of the proposed Pohl impact may have had similarities with the Chicxulub impact on Earth, which previous research has suggested occurred within a region 650 feet below sea level, generated a crater with a temporary diameter of 60 miles , and led to a megatsunami that was 650 feet on land.
