So, after The Big One, how are we to prepare for a massive influx of socially entitled useless consumers of food who can no longer get a check in California?

Is 'The Big One' coming? A California fault capable of a 8.0 earthquake is moving for the first time, study says
USA TODAY Kristin Lam, USA TODAY,USA TODAY 10 hours ago

A California fault that could produce a 8.0-magnitude earthquake began sliding following the Ridgecrest earthquake sequence this summer, according to a study published Thursday in the journal Science.

But the unprecedented movement on the 160-mile-long Garlock Fault isn't the only takeaway, said Zachary Ross, lead author of the study from scientists at the California Institute of Technology and NASA.

"We really have to remind ourselves that California is earthquake country," Ross said. "So, it's not just thinking about the largest, most damaging potential scenarios like events on the San Andreas, but remembering that there's a potential for hazard pretty much all over the place."

About 20 faults created the Ridgecrest earthquake sequence, the study found, by triggering each other similar to dominoes. While each individual fault might not have created the 6.4 and 7.1 shakers on their own, Ross said the potential of multi-fault ruptures needs further attention.

The 7.1-magnitude temblor on July 6 was the most powerful earthquake in nearly 20 years in the Golden State. There has never been a 8.0 earthquake in California; the strongest on record is a 7.9 near Fort Tejon in 1857, according to the state's Department of Conservation.

'Lots of unknowns': Strong storms can generate 'stormquakes,' scientists say

The study was published on the same day the state of California released an earthquake early warning app and on the 30th anniversary of the magnitude-6.9 Loma Prieta earthquake along the San Andreas Fault.

About one-fifth the length of the San Andreas, the Garlock Fault runs along the Mojave Desert in Southern California. The rupture from the second quake in the Ridgecrest sequence ended only a few miles from Garlock, which triggered the fault to begin slowly moving.

How the movement could affect the danger of future earthquakes, Ross said, is to be determined. A large temblor hasn't erupted on the Garlock in about 500 years, the assistant professor of geophysics at Caltech added.

They're not related, expert says: 2 quakes felt in San Francisco area in a matter of hours

With the launch of the California's earthquake warning app, officials encourage all residents to download it as a precaution, regardless of how close they live to major faults.

"There is earthquake risk throughout the state," the FAQ page of the app website reads. "If earthquakes are large enough, the energy spreads far wider than most imagine."

How much advance notice users get will vary depending on distance from the origin of the earthquake, the page says. Those near the epicenter may feel shaking before they get an alert saying: "Earthquake, earthquake. Expect Shaking. Drop Cover and Hold On. Take protective actions."

May be a good time to invest in some ocean front land in Arizona....

Tpap would bust a nut blaming it on "progs".

God. Striking down the modern day Sodom and Gomorrah.We must keep any survivors from coming to well run states (i.e., Republican controlled). We should ship them off to their idea of paradise - Venezuela, Cuba and N. Korea.

I know, right? You need a wall to keep them in, and maybe they'd have to resort to cannibalism.

Study: California's big July quakes strain major fault
Associated Press

,Associated Press.October 17, 2019

LOS ANGELES (AP) - The earthquakes that hammered the Southern California desert near the town of Ridgecrest last summer involved ruptures on a web of interconnected faults and increased strain on a major nearby fault that has begun to slowly move, according to a new study.

Ruptures in the Ridgecrest earthquake sequence ended a few miles from the Garlock Fault, which runs east-west for 185 miles (300 kilometers) from the San Andreas Fault to Death Valley.

The Garlock Fault has been relatively quiet for 500 years. It now has begun a process called fault creep and has slipped 0.8 inch (2 centimeters) since July, the research found.

The study by geophysicists from the California Institute of Technology and NASA's Jet Propulsion Laboratory was published in the journal Science on Thursday, coinciding with the implementation of a statewide earthquake early warning system for the general public.

Southern California's largest earthquake sequence in two decades began July 4 in the Mojave Desert about 120 miles (190 kilometers) north of Los Angeles.

A magnitude 6.4 foreshock was followed the next day by a magnitude 7.1 mainshock and then more than 100,000 aftershocks.

Zachary Ross, assistant professor of geophysics at Caltech and lead author of the paper, said in a statement that it was one of the most well-documented earthquake sequences in history.

Ross developed automated computer analysis of seismometer data to detect the huge number of aftershocks with precise location information, Caltech and JPL said in a press release.

The JPL scientists mapped surface ruptures of the faults with data from Japanese and European Space Agency radar satellites.

"I was surprised to see how much complexity there was and the number of faults that ruptured," said Eric Fielding, a co-author of the study from JPL.

About 20 previously unknown crisscrossing faults were involved.

Ross said the 6.4 quake simultaneously broke faults at right angles to each other, which he characterized as surprising.

It was a commonly held idea that major earthquakes are caused by rupture of single long fault, but that has been reconsidered since a 1992 quake in the desert near Landers, California, ruptured several faults.

The Ridgecrest sequence adds evidence of a more complex process.

"It's going to force people to think hard about how we quantify seismic hazard and whether our approach to defining faults needs to change," Ross said. "We can't just assume that the largest faults dominate the seismic hazard if many smaller faults can link up to create these major quakes."

The study was published on the 30th anniversary of the deadly magnitude 6.9 Loma Prieta earthquake that badly damaged the San Francisco Bay area.

Gov. Gavin Newsom marked the occasion by formally announcing the launch of the nation's first statewide earthquake early warning system.

Alerts previously were made available to schools, government agencies, industries and industries but not the general public, except in Los Angeles County where an app-based system has been in use since January.

The ShakeAlert system that has been under development by the U.S. Geological Survey and science institutions for years will now push alerts to cellphones through an app developed by the University of California, Berkeley, and the Wire Emergency Alert system.

ShakeAlert uses hundreds of seismic sensor stations to detect the start of an earthquake, calculate its location and strength and generate alerts that the app and WEA system send to phones in areas that are expected to have significant shaking.

The intent is to provide seconds or tens of seconds in which people can protect themselves before shaking arrives at their location.

Tens of seconds. Damn. Makes me like hurricane season a little more.

Sadly, California is becoming more and more of a shit hole every day.

Have you read any of the Bleeding Heart Social Justice Warrior articles about PG&E cutting power in fire prone areas?

Well, to get to the point, it seems that the whole "power cutting" thing is just too unjust. The "wealthy" can affort generators and solar power but, all the poor people (every body else) can't afford generators and have to live in the dark.

Well ya, if that is the case and it is so Bad, then move the F out of the fire prone areas.

They've been cannibals from the start. Nothing new with that. California cannibals.

Naw in a couple generations they will all be transblenders honoring the AoC pledge not to procreate; they will be extinct
