Arrows pointing to the Mission Creek strand of the San Andreas Fault. (Uniform California Earthquake Rupture Forecast)
Posted on 03/24/2021 5:15:51 PM PDT by BenLurkin
It's called the Mission Creek strand and it runs from around Indio, through Desert Hot Springs and into the San Bernardino Mountains.
"Higher slip rates on faults mean more risk," said Morgan Page, a geophysicist at the U.S. Geological Survey in Pasadena and one of the developers of the Uniform California Earthquake Rupture Forecast. Page was not associated with the recent study. "It means stress is accumulating faster on that fault and you would need basically either more earthquakes or larger earthquakes over centuries to relieve that stress."
All of which means that this particular strand on the San Andreas has a greater risk than was previously understood.
Any infrastructure in that area, like water or gas lines which run over the fault itself, will need to be looked at with a critical eye, given that offsets of as much as 30 feet could occur in the event of a major quake.
Regardless of what happens on the Mission Creek strand, we know that sizable earthquakes on the San Andreas are possible.
Like... at any moment.

Yet another reason to wear a mask!
Not fast enough - California is still there last time I checked.
What the quake doesn’t destroy, the tsunami will. Stay safe, FRiend!
Had to take a few ‘hard sciences’ classes in college. One I chose was geology. I did a paper on the San Andreas fault. It seemed that the fault (which is many 100s of miles long) has a severe break about once every 75 years... but that after 3 intervals of 75 years it would be relatively calm for about 150 years. Noticed this pattern over several cycles but it’s just an observation. No known reason for it. By the math, it’s overdue.
Do not worry veryt much, after these next 4 years, California will be empty of human beings, only the lefties will be left there.Everyone else will have moved to Florida or Texas.
Soon after the San Andreas quake hits, they will not be missed much.
“Remember the fault line runs right through here...”
Had a friend in Bolinas that lived right on it. I lived in an apartment in SF that shook like crazy during one quake. Elevators out of order, I ran up eight flights. Plaster all over the stairs and in the hall. Woman who had the identical apartment next to mine was screaming she couldn’t get out. I put my back to the door and pushed. Her apartment was a wreck, plaster on the ceiling down, china cabinets...then we went to my door. Opened and gasped. NOTHING. One vase had fallen off the coffee table but didn’t break. I guess my hero cat held the place together.
In SF,, there were so many quakes we could tell whether they were 3.5 or 4.2...I guess we’re overdue for a big one. What do you think? 7.5?
BS If the fault is moving, it’s not building stress.
When it stops, problems build.
Another catastrophe caused by global warming.
Oh darn. That’s a shame.
Yeah if I recall there was a big one in SF in or around 1990 that took out bridges and highways and started fires. Then I think it was 1994 or thereabouts a big one in Northridge (San Fernando Valley) that also took out highways and bridges. My house shook like mad and I had a roommate from NY who was screaming like crazy he had never experienced one before. But only thing that happened was my guitar which was propped against a wall slid over. Roommate wanted to go out for a drive to survey the neighborhood I told him it was a really bad idea. People go absolutely crazy, speed, run red lights etc after a quake. He came back 5 minutes later and said “you were right I should never have gotten in the car”.
But, it turned my 45 minute commute into a 4 hour commute, and then when they figured out how to make one-way roads to bypass the downed bridges it dropped to a 2 hour commute. But the good thing was they paid a bonus, I think it was $100,000 a day, to the builders for every day they could get the bridges done faster than their quoted lead time. Worked out well for everyone except the few who did die (one, a CHP officer was riding when the bridge collapsed under him) and one who was under another bridge when it came down.
If we’re lucky a couple of “small” quakes to relieve the pressure and avoid the big one. But they are unavoidable. The tectonic plates are moving whether we like it or not.
This article acts as if this is bad news.
Cascadia seems to me to be moving on the ends and locked in the middle. I am expecting it to go before the donkey with the stones in his nose sneezes for the third time.
Earthquake stories abound. I was going to have lunch with a friend downtown when he called and said he had to get back to the office in Emeryville. He got there just in time to ask his secretary to stay a minute late and Xerox some papers for him. She might have been dead on one of those bridges that came down.—she was one car behind those killed.
Nice to live in Western WA where the worst problem is fire. Bad enough.
Western Washington is part of the Cascadia Fault zone where the 9.0 is expected.
Need to take out the Fontana, San Bernardino, Rialto crime highway for drug traffickers.
I helped to clean up that area (environmentally) but couldn’t do anything about the criminals.
You’re right. My bad. I live in Eastern WA. Lived on Bainbridge Island for years before moving here. Like it better here, nicer people.
What worries me, seriously, is The Yellowstone Caldera.
That thing is over due to blow and when it does it’s going to be a massive ecological and humanitarian disaster.
