Volcanoes on Mars



     Earth has nothing to compare with the Mars’ volcano Olympus Mons, which rises twenty-two kilometers above its base. Earth’s tallest volcano, Mauna Kea, stands only nine kilometers above the sea floor.

     The weight of the solar system’s most massive volcanic outpouring not only puts a dent on one side of the planet (Mars) but also pushes up the opposite side. These planetary distortions, it now appears, redirected the flow of massive amounts of water early in Mars history that carved large areas of the planet.

     It appears that the planet’s Tharsis region, spanning more than 10 million square kilometers centered on the equator, weighs heavily on the planet. Built by eons of volcanic outpouring, Tharsis sports three massive volcanic shields rising higher than 10 kilometers above the mean elevation…

     Thus, it seems Mars has been beaten up by more than asteroid and comet impacts. These beatings have left Mars with a distorted appearance.


     And who would want to live with such distortion?
