I just looked at some website after thinking that the gravitational forces from the moon and sun lined up would be minimal. For a 180 pound person you will be 1.6 ounces lighter - so minimal.
HOWEVER- that article also stated that the effect on the earth itself is a 40 mm (1.5 inches) change in the crust of the earth causing a small bulge (spread out over 1000 kilometers). I don’t know if that is enough to cause earthquakes, but it is more of an effect than I thought it would be.
Spread the ground apart a bit, more water can go through the materials and into fault zones, etc... Maybe. Although I think a similar thing would happen every time we have a new moon.
But yes, the New Madrid Fault will cause another major EQ some day and cause HUGE amounts of death and destruction. I’m in the Seattle area, so we have our own concerns.
“For a 180 pound person you will be 1.6 ounces lighter - so minimal.”
THAT’s actually a significant effect.
I would have expected orders of magnitude less.
I am small and da Erf is large.
