Mars mega-tsunami may have been caused by asteroid strike, study suggests

According to the researchers, based on Pohl’s position it may have formed around 3.4 billion years ago, based on its position above and below rocks previously dated to this time.

A mega-tsunami on Mars may have been caused by an asteroid strike – similar to the one that wiped out land dinosaurs on Earth 66 million years ago – in a shallow ocean region, a new study suggests.

Past research proposed an asteroid or comet impact within an ocean in the Martian northern lowlands may have caused a mega-tsunami approximately 3.4 billion years ago.
