Six earthquakes hit Southern California in one week. Does that mean ‘The Big One’ is coming?


In recent days, Southern California has experienced one earthquake after another. A 3.6 in Ojai on May 31. Two of a similar magnitude under the East Los Angeles area of El Sereno. Another three quakes near Newport Beach and Costa Mesa.

While these quakes were far weaker than historic temblors like the 6.7 Northridge Earthquake of 1994, which caused an estimated $20bn in damage and killed over 57 people, do they herald the arrival of the so-called Big One in a state sitting on multiple, highly active faultlines?

There’s the notorious 800-mile-long San Andreas, which runs from near the Mexico border, east past Los Angeles, then up the coast north of Sacramento.

Major quakes occur along the fault every 180 years or so, and the San Andreas hasn’t had a majorly powerful one since 1906. The US Geological Survey estimates it has a 60 percent chance of causing a magnitude 6.7 or greater in the Los Angeles area in the next 30 years.

Of even greater concern is the Cascadia Subduction Zone, which runs from Northern California to British Columbia, Canada. It’s overdue for an even larger quake compared with historical averages.

So, are the recent earthquakes an ominous omen of something larger, or business as usual in a state with an estimated 35 quakes a day?

The El Sereno quakes, for example, happened just under the Puente Hills thrust fault, which runs beneath downtown Los Angeles and Orange County. The 10-mile deep fault angles like a ramp and gets closest to the surface near the LA campus of the University of Southern California. If a quake along this fault hits the loose earth of the Los Angeles Basin, it could amplify the intensity of an earthquake by up to ten times compared to areas located on bedrock.

The Newport Beach-Costa Mesa temblors, meanwhile, took place near the Compton thrust fault, which could raise the LA River by up to 5 feet in a strong quake, wreaking havoc on city sewer systems. There have been six quakes above magnitude 7 along the fault in the last 12,000 years, according to geologists.

Scientists argue that instead of focusing solely on the largest quakes by magnitude, the key consideration is how much damage they could do to densely settled areas. The San Andreas, despite its famous reputation, runs for large sections through sparesly populated desert.

“In some respects, the ‘big one’ in terms of damages and deaths would be ones running through town rather than one that’s a long distance away,” Dr. Pat Abbott, professor of geology emeritus at San Diego State University, told KSWB last year. “There’s the size of the earthquake, and then also where you are situated compared to where the fault’s moving.”

He pointed to major quakes like the 1857 and 1906 San Andreas earthquakes, as well 1994’s Northridge earthquake, all of which were under the 8.0 magnitude contemplated in “Big One” scenarios but which still caused “horrendous” damage.

“Unfortunately, earthquake prediction remains an extremely challenging endeavor,” according to the California Governor’s Office of Emergency Services website. “While scientists can monitor fault lines and detect patterns of seismic activity, they cannot predict exact earthquakes reliably.”

Instead, scientists deal more in the realm of long-term probability, which can inform what high-risk areas can do to prepare for the day when the hard-to-predict prospect of a major quake arrives.

For instance, the USGS estimates that there’s a 72 per cent chance a 6.7 or greater magnitude quake will hit the San Francisco Bay Area in the next 30 years.

Finding a greater level of precise prediction is the “holy grail” of earthquake science, University of Washington seismologist Harold Tobin wrote last year.

“Science has not yet found a way to make actionable earthquake predictions,” he wrote. “A useful prediction would specify a time, a place and a magnitude – and all of these would need to be fairly specific, with enough advance notice to be worthwhile.”

In the meantime, until that magic predictor code is unlocked, governments can push for preparedness measures like digital alert systems, practice drills, and building retrofits, while individual citizens are advised to have emergency kits in place and drop to their knees, cover their head and neck, and hold onto something stable when a quake begins.

California bill would let insurers monitor driving data for discounts

California bill would let insurers monitor driving data for discounts


A California bill would let insurers monitor customers’ driving data in exchange for discounted premiums.

Assemblymember Tina McKinnor, the author of AB 311, said the digital monitoring, known as telematics, rewards good driving and would improve safety. In real time, telematics technology would track data such as speed, location and how a vehicle is being driven.

“We have to slow people down,” McKinnor said. “That is the whole purpose for this bill, is driver safety.”

A voter-approved law from 1988, Prop 103, required insurance rates to be based mainly on driving record, miles driven and experience. It made California the only state in the country to prohibit telematics.

McKinnor believes the law is outdated. She argued that her bill would also help good drivers who pay higher rates because of where they live. 

“Where I live definitely brings my insurance up,” McKinnor said. “If we both drive the same way, we’ll get charged the same way, instead of by our ZIP code.”

California’s Department of Insurance and consumer groups oppose the bill, citing privacy concerns. 

“We can’t look behind the algorithm and see what weight it’s giving to different criteria, which is a big problem,” said Jamie Court, president of Consumer Watchdog. “Auto insurance, otherwise, is transparent. This is why the Department of Insurance is opposed, because of the lack of transparency in the algorithm.”

The proposed savings in exchange for good driving might not be guaranteed. Telematics data from the Maryland Insurance Administration showed that 31% of drivers who opted into the program saw a drop in rates, 24% saw an increase and 45% saw no change to their premiums.

“This collects an awful lot of data about people, more than they know, and it’s like having Big Brother in your back seat,” Court said. 

McKinnor insisted that drivers will not be forced to enroll in the program. 

“It’s still opt-in in the other 49 states,” she said. “We’re not going to make this mandatory. It’ll be a per-volunteer situation.”

McKinnor’s bill passed through the legislature’s insurance committee. It’s expected to be presented to the full Senate in August.

Southern California police vow to quash planned ‘takeover’ event following recent chaos


Huntington Beach police are vowing to prevent a potential “takeover” event being promoted across social media that they believe could get out of control.

Police said they became aware of the event from a flyer online advertising an “end of summer beach bash” in the city.

“Dear ‘Beach Bash’ organizers…” police said in an Instagram post Thursday. “Thanks for the flyer. We’ve seen it too.”

They continued, “We have no intention of allowing that to happen here.”

No further details were provided about when the event was planned to take place or the exact location.

Police and the city of Huntington Beach said they’re working to prevent the event following similar events in Southern California that resulted in violence, vandalism and other criminal activity.

One chaotic event that was held in Newport Beach on the Fourth of July ended with more than 400 people being arrested, according to police. Some partygoers were seen fist fighting, while others allegedly vandalized property and local businesses, including a Pavilions grocery store.

Newport Beach police said social media posts drew a large influx of people to Newport Pier in a short amount of time, and the event got out of control.

Huntington Beach PD warned that anyone who organizes, promotes or participates in criminal activity associated with a takeover event may be arrested or prosecuted. Charges may include incitement to riot, vandalism, theft, assault, reckless driving, unlawful assembly, conspiracy or other applicable offenses.

They also warned that juveniles would not be exempt from punishment, and parents or guardians may also be liable for damages caused by their child’s actions.

The HBPD Special Investigations Bureau has already identified individuals believed to be involved in organizing and promoting the event, according to police.

If you have information regarding this event, you are urged to contact Huntington PD’s Special Investigations Bureau at 714-536-5991.
