But what you're really looking for is statistical info on how hard the Moon and Mars each pull on the Earth at their respective minimum distances.
Here's a hint -- try searching on this list of keywords: "gravitational pull" Mars Moon Earth maximum minimum
What causes the flow of magma, and periodic flow near the surface, which we correlate to volcanic explosions, and whether these changes in the flow of magma/volcanic explosions have a correlation to other events in the solar system, specifically the nearness of other planetary bodies to the Earth, and whether the change in magma may be a force of gravity, or whether it may be some new unknown force.
