Such a quake would send strong shaking almost simultaneously into Los Angeles, Orange, Riverside, San Bernardino, Kern and Ventura counties.The prospect has fueled efforts by California’s local governments to strengthen earthquake retrofit laws. In general, there’s a 20% chance of a magnitude 7 or larger quake on this part of the San Andreas fault over the next 30 years. The Bay Area native is a graduate of UC Berkeley and started at the Los Angeles Times in 2004.For 10 years, downtown L.A. was booming with a youthful, renegade vibe. A new study suggests that last year's Ridgecrest earthquakes increased the chance of a large earthquake on California's San Andreas fault. “So this is probably too far away,” she said, for Monday’s quakes to trigger a large one on the San Andreas. A swarm of small earthquakes in California, close to the Mexican border, is being closely monitored as to whether it might raise the chance of a much larger event on the San Andreas fault. “This is 100 times higher than its annual chances in the ‘UCERF3’ benchmark model for California, which is jointly issued by the [U.S. Geological Survey], the Southern California Earthquake Center, and the California Geological Survey,” Stein and Toda wrote.The scientists calculate that if the Garlock Fault ruptured to within about 30 miles of its junction with the San Andreas Fault, “it would raise the probability of a San Andreas rupture extending to the southeast, on the so-called ‘Mojave section,’ by a factor of about 150.”“That translates into a 50/50 chance of a San Andreas Mojave section rupture (with a range, 25 percent-67 percent), either immediately following a Garlock quake, or after some delay,” they added.Set against this backdrop, they estimate that the net chance of a large San Andreas earthquake in the next 12 months is 1.15 percent.
“While small, this probability is 3.5-5.0 times higher than the annual chance of a large San Andreas earthquake in the ‘UCERF3’ benchmark model for California,” they added.Given the small likelihood of a large San Andreas earthquake in the next year, the scientists say no one should panic.“But, as we have seen during the COVID-19 pandemic, low probability chain-reaction events do occur in nature, and when they do, their consequences can be great,” they explained. We use past seismicity, the stress imparted by recent large and moderate earthquakes and the equations governing how fault friction varies in time and space (‘rate-state friction’) to estimate the likelihood of future earthquakes of different sizes.”The experts used machine learning technology in their analysis, which estimates a 2.3 percent chance of a magnitude-7.7 Garlock Fault rupture in the next year. It started in Monterey County but rushed down to Los Angeles County in about two minutes, sinking trees in Sacramento and uprooting trees near the Grapevine section of Interstate 5. ‘We’re going to be more stubborn this time,’ he says.A 37-year-old man has confessed and written an apology for stealing a firefighter’s credit cards and racking up more than $1,400 in charges, officials say.TikTok stars Bryce Hall and Blake Gray are charged with misdemeanors for allegedly holding large parties in the Hollywood Hills during COVID-19.

And it’s going viral because of it.Among the failed measures was a law that would have required fellow officers to intervene when they witness excessive force.California bill would end single-family zoning by allowing duplexes on single family parcels. “It’s not so much too far away that you say it’s impossible. — temblor (@temblor) July 13, 2020 The scientists calculate that if the Garlock Fault ruptured to within about 30 miles of its junction with the San Andreas Fault… Southern California’s last megaquake, a magnitude 7.8 in 1857, was on the San Andreas fault and was preceded by smaller quakes on the northern terminus of the southern San Andreas fault, in Monterey County. “But every time it happens, we do worry that this could be the time that it triggers something.”In any given week, there’s a 1 in 10,000 chance of a magnitude 7 earthquake on the San Andreas fault. Perhaps the most famous example of triggered earthquakes in California occurred in 1992.An April 22 magnitude 6.1 earthquake in Joshua Tree National Park began a sequence that migrated north in the following months.
