I propose a simple test of this idea.

I will determine the sun-moon angle for every mag 6+ quake in the NEIC catalog and sort them by 5 degree blocks from 0 to 180 degrees.

If there is such a relation, there should be more quakes at certain angles. 0, 90 and 180 are most commonly suggested.

If not, the idea is refuted.

Any comments?

Well this is interesting. I sorted all those quakes into 5 degree bins and counted the number per bin, added them all up and divided by 36 to get the expected average. Then I computed the standard deviation.

To my surprise, it was WAY too big, indicating that these were not random variations at all. But the highs did not represent any expected positions. The largest number was in the 70 degree bin. The next largest was the 85 degree bin and the third was the 150 degree bin. None of these would be expected under any "theory" I've seen proposed.

Any ideas out there?
