Not much happened, no major earthquakes, or clusters of minor earthquakes. Well, astrologer Richard Nolle actually cleared up his definition of what a “supermoon” is (compare with the wording here).
It turns out it’s any full Moon with a perigee closer than 361585 Km (a bit closer than the average perigee distance of 357372 Km). The justification for this distance is pretty much non existent, but even the closest “supermoons” have a tidal force only 4% greater than the “supermoon” cutoff. Also, recall that in Astronomical terms “Full Moon” is when the Sun and Moon are exactly aligned. For us ordinary folks wandering out in the evening, Full Moon is from Moonrise to Moonset on the night of the Astronomical Full Moon and I think this is the form of “Full Moon” that Nolle is using. In terms of wandering out and looking up at the Moon (and failing to see any actual difference without a telescope and a photographic record), this is perfectly okay.
Well worth a read and seems to knock the moon/earthquake theories fairly squarely on the head.
I still think a longer term study needs to be done, and as always I am not impressed by magnitudes and would prefer these things compared to energy, but overall a good article well presented.
