First, since you've now raised this point twice: Your outrage that I didn't contact you before I did a podcast that included parts of an interview you gave is, well, let's just say somewhat confusing. Do you honestly expect anyone who writes something that mentions someone has to contact them first? Did you contact anyone at USGS before you went on Coast in November and ranted against them for several minutes? Under your logic, you should have done so to allow them to comment before you went on. I suggest you harbor your emotional energies. I also suggest that your ranting against USGS and numerous other blatant logical fallacies (non sequiturs, argument from persecution, argument from authority, argument against authority, argument from personal credulity, misuse of statistics, correlation = causation, remembering the hits while forgetting the misses, data mining) do not help your case.
But now, more to the point: the data. The data should speak for itself. Even if someone can point to a hypothesis for why something should happen, if the data don't show it, then it needs to be rejected or significantly modified.
I count 29 earthquakes using your definition of southern California, though since 5 of those occurred within 1 day of another, they could probably be considered duplications or after-shocks or just parts of the same one but with a large epicenter -- I chose the bigger of the two. That's still 24 earthquakes.
Of those 24, I count 8 that occur during the 6 hours that you define as "dawn" or "dusk" (4:45-7:55 AM or PM). Considering that you're blocking out 6 of 24 hours, one would expect 25% of the 24 earthquakes to occur during that time by chance, which is 6.0±2.4 earthquakes ... basically a ~1-sigma result, which is well within chance.
I then went through and manually found the closest perigee, new, and full moons to each of the 24 earthquakes. And absolutely positively ZERO of the earthquakes were within one day of BOTH a perigee AND (new OR full) moon. I found 3 that happened within a day of a new or full moon. When you define a "hit" as a 4 of 28-day window (±1 day of a new moon, ±1 day of a full moon), then the chance is 14.3%. 14.3% of 24 is 3.4±2.6 expected, and the result is 3±1.7 ... a 1-sigma result, well within chance. If you reduce the window to ±0.5 days surrounding a new or full moon, you're talking about 2/28, or 1.7±1.3 earthquakes expected, and the actual data are 2±1.4 ... again, a 1-sigma result, well within chance.
I found that 3 occurred within ±1 day of perigee. Perigees happen roughly once every 28.5 days, so when you define a ±1 day window, you would expect 3.5% to fall within it, which is 0.84±0.92. A sample of 3 is a 2-sigma result, which means that there's a ~5% chance of that happening randomly. However, these earthquakes that occurred near perigee were 2.4, 3.7, and 3.3 days from a new or full moon.
Similarly, only two of these that happened near a new or full or perigee moon were within a month of perihelion, when the tides from the sun would be largest ... shouldn't there be a pattern of more earthquakes when we're closest to the sun?
I also count only one earthquake that occurred within dawn or dusk and a full or new moon, and I count two that occurred within dawn or dusk and a perigee moon.
For ZERO of the earthquakes was there both a perigee and new or full moon within 24 hours of each other and the earthquake. There was, however, one earthquake that was within 33.6 hours of a new and APOGEE moon, when lunar tides are at their minimum, AND when Earth was farthest from the sun. It occurred 13 days after a perigee and full moon (within 0.94 days of each other). There was a time an earthquake occurred 2 days after a perigee and full moon that were within 0.05 days of each other, but the quake was 2 days later.
The data for new and full moons comes from
the Lunar Perigee and Apogee Moon Calculator.
