The effects of the comet on Earth at closest approach will be as inconsequential as that of a mosquito slamming head-on into an ocean-going supertanker.
Let's look at the physics. Comet Elenin is a loose agglomeration of volatile ices and dust a few miles across. It is therefore one hundred billionth the mass of our moon. (The relative difference is roughly the same as the mass of a mosquito vs. the mass of an oil supertanker.)
The comet will pass no closer to us than 84 times the Earth-moon distance.
Applying Isaac Newton’s laws of gravity, this means the comet's tidal pull on Earth -- at closest approach -- will be approximately one-hundred trillionth the force of the moon's tidal pull on Earth. And, we all now know that despite the dreaded Supermoon hype last week, there were no monster storms or earthquakes triggered by our satellite's gravitational tug at closest approach to Earth.

Could planetary alignments with Comet Elenin be causing big earthquakes? Based upon the above, I doubt it.

That is, assuming that Elenin really has this mass and size they are saying. I doubt it. I think it is much bigger, but I have no evidence or thought on it, just throwing it out there as a bait for trolls.

I would think that an alignment with Mars or Venus, and especially Jupiter, would have a much bigger effect than some comet/planet/brown dwarf that is much further away.
