been observing those big ones creeping up the coast on that ring of fire.
actually watched this one live on the ABC cam. They show up on that local Los Angeles cam with what I call a “ Etch a Sketch” pattern. I went to the USGS site and sure nuf... there it was a 7.5 in Mexico.
About the same time of the year that the big one hit in North Mexico on Easter Sunday several years back.
A scary thing that happened in New Zealand is that if the soil has a high water content it can liquify in a strong quake.
There is a geologic theory that says very large quakes cause slow cascade ruptures.
“Earthquake Alert” app has me monitoring movement 24/7.
CA/OR/WA is the only area on the Ring of Fire which has been fairly quiet since 2004 Indonesia.
