Magma Tidal Effects?

It is a bogus theory. Not worth considering for even a moment.

There are so many other variables...it's pointless. The Christchurch and Japan earthquakes were out of cycle for the "Super Moon" we had. My daughters came home from school saying how all of her friends were talking about it and they even discussed it in science class...imagine that...that's good scientific process, I tell ya.

Anyhoo, if one were to measure the actual linear pull at instantaneous values, one would find very little to hypothesize on. It's fast food science...kinda like astrology (not really). There is an effect, but there are millions of other effects which have just as much and definitely more influence in the equation.
