The equator is being pulled by the moon and sun for a millennium, its noticed here as tides, and no real noticeable changes have occurred. As far as
outside forces pulling on earth, I can link you to the numbers, but they will reveal insignificance, to outline, Jupiter accounts for more than half
of all the planet's tidal force on earth and is about 1% the tidal effect the moon has, if all the planets somehow aligned to on side of earth they
would have about 1.7% the tidal effect the moon has. It a relatively simple mathematic equation.
Wobble and rotation are two different things. I don't believe the numbers the Japan earthquake had on the equatorial circumference, I don' think
there's a relationship there. What I found, and happens all the time, is the recent Supermoon back in March expanded the earth's equator by roughly
9-10 inches for a brief period. I think a figure of 6 inches is normal for full moons not super.
Plate shifting does not increase the mass of earth, its a live planet and always has been recycling its crust..
