I've heard stuff like this before years ago but I thought it was more along the lines of an old wives tale:

A full moon may have triggered the Indian Ocean earthquake that caused the tsunami on 26 December 2004, a new study concludes.

Yeah cause it exerts more of a gravitational pull when more of its lighted side is pointing at us . . .:physics:

It seems like a credible theory to me.

I saw a documentary on this about 3 weeks ago.

The part I had heard as a wives tale before was earthquakes after heavy rain. I think I was on an earthquake discussion group back in my Usenet days.

It seems like a credible theory to me.

I got one of these things back when I was a kid.

It burned into my mind that light does in fact have mass, that photons have mass at an early age.

If light has mass, then the mass of the photons of the sun, bouncing off of the moon, could actually cause tectonic shifts.

It can probably turn people into wolves too, but we never see them because they fall into the cracks in the earth.

On photons having mass:
The overwhelming consensus among physicists today is to say that photons are massless. However, it is possible to assign a "relativistic mass" to a photon which depends upon its wavelength. This is based upon an old usage of the word "mass" which, though not strictly wrong, is not used much today.
In one sense, any definition is just a matter of convention. In practice, though, physicists now use this definition because it is much more convenient. The "relativistic mass" of an object is really just the same as its energy, and there isn't any reason to have another word for energy: "energy" is a perfectly good word. The mass of an object, though, is a fundamental and invariant property, and one for which we do need a word.
