Ben Davidson shows some new evidence suggesting that the crust of Mars moved over its interior in a pole shift, which other scientists have long attributed to the mass imbalance of the solar system’s largest volcano, Tharsis Mons – moving from it’s original location towards the equator by as much as 50 degrees (one article suggests a large move early on, then another in the opposite direct later that left the overall movement much smaller) or possibly a difference of 20 degrees (after multiple pole shifts, one caused by the eventual loss of oceans) as suggested at Wikipedia and as shown on maps of magnetic features paralleling surface features in the video below. It should go without saying if pole shifts happen on Mars they can happen on Earth.
