Just go talk to your local Police/Fire/EMS/Hospital people.
Things go bonkers on full moons.
And that's completely irrelevant to earthquakes.
Just as in the supposed lunar phase/earthquake supposition, studies I've seen show there is no demonstrated relationship between full moons and crime/physical violence.
There are seasonal variations however! It's documented for example that there is more family violence during the Thanksgiving - New Year period than in any other similar length period during the year.
