Big One Closer Than Ever: San Andreas Fault Now Hitting Record Tectonic Stress
Red State ^ | June 16, 2026 | Ward Clark

Posted on 06/16/2026 4:40:26 PM PDT by Red Badger

There's a reason they call the lands surrounding the North Pacific the "Ring of Fire," and no, it's not because of a Johnny Cash song. No, the reason for that appellation is that the northern coasts of the lands on the Pacific are hotbeds of tectonic and volcanic activity. Nowhere are Americans more aware of this than in California, which has been hit by some pretty serious temblors in the past.

Now, it looks like another big one may be on the way. Geologists are looking at the San Andreas and San Jacinto faults, and they are a tad worried about what they are seeing.

The San Andreas and San Jacinto fault systems are at their highest levels of tectonic stress in 1,000 years, raising the threat of a major, imminent earthquake that could devastate Southern California, a new study finds.

The faults could rupture separately or together, thanks to an "earthquake gate" between them at Cajon Pass, where the San Jacinto fault splits from the main trace of the San Andreas fault. Researchers discovered that the Cajon Pass can prevent or facilitate earthquakes moving between the faults, depending on how similar their stress levels are at the time of rupture.

And right now, the San Andreas and San Jacinto faults appear to have comparable, extremely elevated stress levels, potentially spelling trouble for Los Angeles, San Bernardino, Riverside and the Coachella Valley, the team warned.

It's happened before, and if it happens again, well, there are a whole lot more people living now in the area that's likely to be affected by such a quake.

The San Andreas and San Jacinto faults have caused 36 earthquakes with magnitudes of 6.4 or above in the past 1,000 years. Southern California's last "big one" was a magnitude 7.9 event in 1857, when a 205-mile (330 kilometers) segment of the San Andreas fault slipped horizontally between Parkfield and Cajon Pass. That rupture did not propagate through Cajon Pass, but a similar megaquake in 1812 did, suggesting this could happen again in what is now a much more built-up and densely populated environment, according to the study.

California won't drop into the sea; neither of these is that kind of fault. But boy, howdy, talk about billions in property damage, not to mention lives lost.

Here's the thing: The study referred to here presents possibilities ranging from bad to apocalyptic, but there's little in the way of expected time frames. Yes, there is some serious stress building up along these faults, and yes, if they let go, results could be very, very bad indeed. But geologic time isn't like the human timescale we're used to; "soon" in geological terms might be tomorrow, it might be a thousand years from now. Although, from my own modest education in geology, it would seem the former to be more likely than the latter.

If you're in California, taking any fragile glassware down from open shelving and packing it securely away may not be the worst idea ever.

This seems appropriate.

And on that day people from San Bernardino will be able to surf to Nevada.

I was in Loma Prieta and it was only 7.2

The next one should be a doozy

Glad we left in late 1970.

Felt a big one at 8 years old near Ventura.

If everything west of the fault slid into the ocean, California would be crimson red MAGA country.

Of course, we'd only get two House seats so there's that.

maybe MamaEarth is just flexing her muscles to get rid of a lot of blight, physical and political?

seriously, though,
sometimes geologists say such faultline activity is good because it releases stress in small non-destructive mini-quakes...............and other times geologists say similar faultline activity is bad because it is “leading up to” THE BIG ONE

so I get confused

I wonder how widespread the future quake will be.

When I was in Croatia in the 80s I was in a small tremor it was the weirdest feeling , I was in bed at the time just falling asleep , only time in my life ever in any quaking ,LOL

Very likely.
There has been huge movement everywhere on the ring of fire in the last 20 years except the LA to SF fault.
I am watching closely every week.

It is slipping north of course.

No loss, as Oregon and Washington are already infested with liberalism and apparently a lost cause as is Calif.

in a long time they can all sing kumbaya and have a circle jerk.

San Andreas Fault

Don't blame someone else for your own problems.

Note this study is not based on any actual measurement using some sort of sub-surface stress gauge.

It's based on a model using data of prior quakes and slip rates, which are generally known and actually measured (mostly).

When we live in CA, both in Santa Monica and San Francisco, we went through so many quakes we could accurately say, “That was a 4.5 and “That was a 3.9. They stopped being terrifying very soon after we moved there. HoHum. Knew when we had to hold rhe full-lwngth mirror to the wall, etc.

Quakes were kind of fun in the bathtub, though.

If we are amazed at the number of millionaires launched by Musk, just wait and see the number of millionaires in government when the big one occurs.

I’m sure Sacramento will be calling DC before the shaking stops - “We need $10,000,000,000,000 immediately, it’s a national emergency!”
