my main worries concern if this cascades or is a precursor to the major faults moving.

Here in San Diego county we are far away maybe 150- 200 miles and even a major quake in Rridgecrest area would hardly be a concern to us physically.

But off the coast inland you could draw a line from sea of cortez / gulf of california up past salton sea which is maybe 60 miles away north and that's the San Andreas, the edge of the pacific plate and thats actrually the big dnger here and especially since there is a huge geothermal plant there which is the most dangerous thing in opinion of many scientist could be affecting the whole shebang.
see: https://news.ucsc.edu/2013/07/geothermal-earthquakes.html

Of course huge dangers lurk everywhere on the this side of the pacifc rim.
The main ones otherwise are like for instance what is considered the most dangerous area for tsunami generation thus my concern over M 6.2 - 196km WSW of Bella Bella, Canada that area is predicted to spawn a possibly Mega tsunami at some point in possibly my lifetime (say 20-30 more years?.




Not to mention we have some of the most dangerous volcanoes up north there starting at area by Mt st. Helens Lassen, Shasta etc.which alone could make mega bursts at any time.

I'm actually more concerned about this: M 3.0 - 14km NE of Thousand Palms, ...W 14.4 19 km (12 mi) ESE of Anza, CA




just because of the aforementioned. Although I have to say small quakes happen everyday around there to mexical its not unusual per se.
