Does a full moon send more destructive light waves?Here's the relevant section from the Wikipedia entry on tides:
Approximately twice a month, around new moon and full moon when the Sun, Moon and Earth form a line (a condition known as syzygy[8]) the tidal force due to the Sun reinforces that due to the Moon.I'm not convinced that this would make a significant difference on the occurrence of earthquakes, but it isn't a crackpot notion (as you suggest).
I agree that it’s not a crackpot notion. The Moon/Earth system has a strong internal gravity effect on itself (does that make sense?). You can see it in the tides.
The Sun has a much more moderate effect. If we didn’t have a Moon, there would still be small tides.
Everything else in the Universe might as well not be there gravitationally. They are insignificant as far as tidal effects are concerned.
SYZYGY. One of my favorite Astronomy terms. One of the former members of our club had that as his license plate.
