Study suggests earthquake fault could shake up Orange County’s future

Good morning. It’s Wednesday, Sept. 28. I’m Carol Cormaci, bringing you today’s TimesOC newsletter with the latest roundup of news and events.

Maybe you saw this L.A. Times headline the other day and, like me, wondered if we were all doomed to be swallowed up by Mother Earth at any moment: “Fault along L.A., O.C. coast could unleash huge earthquake on scale of San Andreas, study shows.”

The phrase “huge earthquake” tends to give me pause. I’ve resided a little too close to a couple of good-sized shakers in my lifetime (one was a magnitude 6.1 and the other 6.7), but so far have lived to tell the tale. Neither of those, however, could hold a candle to the potential experts see in a seismic event along the Palos Verdes fault zone, according to this report by one of our colleagues, Salvador Hernandez.

“Scientists found the fault could produce a quake of a magnitude comparable to one from the San Andreas fault,” Hernandez writes. “Earlier estimates said the fault zone could generate up to a magnitude 7.4 earthquake, but the new study shows it could produce a quake as strong as 7.8.”

As the name of the fault suggests, it runs deep beneath the Palos Verdes Peninsula in L.A. County, but “it’s a system of interconnected, closely spaced planar fractures stretching from the Santa Monica Bay to the waters off Dana Point,” Hernandez reports.

This brings the specter of significant damages a little closer to home, at least to those living in coastal Orange County.

“Caltech seismologist Egill Hauksson said a 7.8 quake on the Palos Verdes fault would devastate Southern California,” Hernandez writes.

Uh-oh, that doesn’t sound good.

I pushed on reading the article. This is not to discourage anyone from taking this news to heart and making sure their earthquake supply kit is up-to-date, but I think it’s safe not to panic. At least not about this particular fault zone. Yet.

Hauksson, whom Hernandez describes as one of the region’s most respected experts in this field, said a potentially massive quake along that fault zone would be unlikely to occur in our lifetime.

“It would be pretty devastating, but it’s pretty unlikely,” Hauksson told Hernandez. “It’s not a very active fault.”

Tropical Storm Kay last month brought rainfall and high surf to the coastal areas of Orange County, shifting sands and shifting the railroad at San Clemente, according to this story by L.A. Times reporter Grace Toohey. The immediate result was the short-term delay of some Metrolink service along the line. Officials say that stretch of coast is caught precariously between an “ancient landslide” and severe sand loss from erosion, development and climate change. When the Sept. 9 shifting action was reported, Metrolink added 1,600 tons of boulders between the rail lines and the ocean, Metrolink spokesperson Scott Johnson told Toohey. He expects more to be added through this Sunday.

— A gift store, perhaps not surprisingly, is one of the elements to the new Orange County Museum of Art, which will open its doors to the public next month. The store, given the name the Mind, according to this story by my colleague Sarah Mosqueda, will foster a connection between OCMA and its neighbor, South Coast Plaza. There will be five distinct sections to the retail operation, from a Vintage Gallery to more contemporary offerings. All will be centered around a functional art piece made of stainless-steel mirrors with a hidden soundtrack created by French artist Sébastien Léon. For a sneak peek of the $94-million OCMA, check out these L.A. Times photos.
