Mars Had Landslide-Powered Tsunamis That Put Earth’s Mega-Waves to Shame

by Nola Taylor Redd/Smithsonianmag.com

Billions of years ago, a giant landslide cascaded down the slopes of the largest mountain in the solar system—Mars’ Olympus Mons. When all this material fell into the water of Mars’ (probable) ancient ocean, it created a towering tsunami stretching between 25 and 43 miles long that crashed against the shore of the planet’s northern hemisphere.

A new study in Planetary and Space Science identifies the remnants of this long-ago event. The landslide-induced tsunami would have required a large body of water, yet more evidence for the case in favor of the existence of a long-disappeared Martian ocean.

Martian tsunamis are not a new idea. In 2015, researchers showed that impactors from space had splashed into the planet’s ancient ocean and kicked up giant waves. The newest findings could also help planetary scientists pin down how big the ocean might have been.

Landslide-generated tsunamis are common on Earth, says Fabio Vittorio De Blasio, a scientist at Italy’s University of Milan and the author of the new research. To show the same thing could’ve happened on Mars, De Blasio studied satellite images of the planet’s topography, more specifically the remains of the enormous landslide. ….read more:

  1. They reached the canal. It was long and straight and cool and wet and reflective in the night.
    “I’ve always wanted to see a Martian, said Michael. “Where are they Dad? You promised.”
    ‘There they are” said Dad, and he shifted Michael of his shoulder and pointed straight down.
    The Martians were there. Timothy began to shiver.
    The martians were there-in the canal-reflected in the water.
    Timothy and Michael and Robert and Mom and Dad.
    The Martians stared back up at them for a long, long silent time from the rippling water…………..

    • Yes, but what was there before that happened?
      Some very strange and unnatural formations have been discovered there.
