California has a birth time. I went back through some of California's biggest earthquakes to see what patterns were showing up.
And as Jupiter is coming to hit The Californian's North Node, the chart of coming Eclipse is high in triggers for potential earthquake.

Earthquakes and fate?

I chose to work THE CHART OF CALIFORNIA first.

And we are lucky California has a birth time.

I went back through some of California's biggest earthquakes to see what patterns were showing up. And the most obvious is:

The nodal axis is hit every time but once. 14° Fixed axis. World Point

And the natal square Chiron 2nd house, Neptune 4th house is activated as well. So any planets coming around the 5 ° Mutable axis is a potential trigger. World point too!

Which is the Eclipse degree and Uranus just saying.

At the end I am showing you California's chart for the coming eclipse in Pisces, and you will see: there is A LOT happening there.

THE WINDOWS AHEAD

Jupiter is coming to conjunct California's North Node. Jupiter is also involved in all the cases below.

Jupiter won't come back there in retrograde exactly, but It will station at 3° orb at 17° Leo.

And when the Nodes gets closer to their reversed return, if we work with a 4–5° orb, this gives us another potential earthquake window.

More precisely, end of October: Mars on the North Node and a lot of the triggers we have around the eclipse as well.

Mid-April 2027: Nodes and Jupiter conjunct around 17° Leo, Aries season, Saturn return, the Sun activating Uranus/Pluto with Chiron almost there too, and Pluto on Lilith.

What I did not do

I haven't taken the time to check the charts of each major California city, or the astrocartography lines of these transits, on purpose. That would be another layer of research and prediction I don't want to get into.

I just looked at the astrological patterns showing past and future.

And we live in California. The possibility of an earthquake is never very far away anyway, So these potential event charts are just timing higher probabilities than usual. A whole lot higher to be honest.

And I didn't do a complete exhaustive research either.

First are the charts for the past earthquakes in California and next, the charts for the 3 windows I found for the potential coming earthquakes, during a 1,5 year research window: within the nodes in Aquarius/Leo axis.

These are two other dates I could see as higher risk.
