Any sciencefags/geofags here? your knowledge is recquired to answer a very important question: how big/strong would a Pokémon like Tyranitar or Groudon, or something else (for sake of being cool, let's say a monster, a pocket one if you will, but anything really) have to be to realistically create an earthquake by walking or stomping (if that's even possible, I don't know shit about earthquakes)? or alternatively, and to be math friendly, how big of a force against the ground is needed to generate an earthquake?
