There will be a total eclipse on October 27th of the coming month.
Although seismologists often discount telluric influences on the Earth's seismicity they do suggest that the same influences that cause neap and spring tides can also effect seismicity. This is to say that a theory such as the "Jupiter Effect" posited by one astrophysicist a number of years ago (1980 when St. Helens erupted to be precise), may be discounted as probable bunk or just coincidence - while the effects of the moon's cycle are generally granted to be observable.
Is it a coincidence that the recent activity east of Mono Lake and under St. Helens and the quake yesterday in Parkfield followed by a category 5 some distance away between Lake Isabella and Bakersfield late this afternoon - and could these be related to the coming eclipse or the combined effects of sun and moon when the moon's orbit is concentric with the celestial eqator at the same time that it conjuncts with the sun? Lunar eclipses generally occur in this same cycle if I'm correct.
Additionally I'm curious. Why is it that Meteoroligists and Oceanographers will grant the influence of the coriolis effect on the weather and sea currents, but geologists seem much less certain that it is influencing the magma and the earth's molten and solid cores?
Obviously the continents do get in the way of it. But how much?
I also wonder how the notion of the earth having a solid inner core could possibly be more than theory.
All thoughts are welcomed.
I'm looking at my statement realizing that I have it backwards.
The eclipse, as I mentioned has not yet occurred unless there was a lunar eclipse in this cycle which is possible, but I know there was none here in Northern CA - at least not that I was aware of.
I hope I'm not being prophetic. The USGS Map is looking rather active:

I was looking at the wrong month.
The moon was just full and indeed moving towards a neap spring tide cycle. All the motion in CA does seem to be occurring in advance.
And the eclipse on the 27th is a lunar eclipse. Those do occur more frequently than solar eclipses because the earth occludes the moon from the sun which is what allows the red spectrum light that refracts through the earth's atmosphere to cause the moon to glow with the atmosphere acting as a sort of lens.
The tides for certain will be both lower and higher this cycle. It's a good time to look for bodies out in Richmond Bay. Neap tides leave the bottom showing considerably further out at this time than normal.
