Previous studies have found that two meteorite impacts may have both triggered a large tsunami on Mars about 3.4 billion years ago.
The former tsunami flooded an area of about 800,000 square kilometers, while the most recent tsunami flooded an area of about 990,000 square kilometers.
And a 120 km giant crater, Lomonosov Crater, found on the Martian Arctic ice sheet
This may have been the starting point of the most recent major tsunami, and the size of the meteorite that caused the impact may be similar to the size of the meteorite that caused the extinction of the dinosaurs and nearly 75% of all life on Earth.
According to a recent new study, scientists may have discovered the 111-kilometer-wide Pohl Crater, the starting point of a much earlier tsunami.
Based on data collected by NASA’s Viking 1 spacecraft from the landing site, Chryse Planitia, a smooth circular plain in the northern equatorial region of Mars, scientists have found that the plain is filled with a large number of rocks.
Scientists have found that the plain is covered with boulders, and these may be the remains of a large tsunami that took the crushed rocks away from the impact site.
And 900 kilometers from the “Viking 1” landing site of Ball Crater is the most likely starting point for tsunami generation, the wave may initially extend to about 500 meters high, measured on land about 250 meters high.
One step toward studying what may have happened to the ancient Martian ocean between the two large tsunamis, and what may
Subsequently, the researchers wanted to enter what potential biological effects were generated.
The study was published Nov. 1 in Scientific Reports.
