The ground is literally disappearing. If you drive down Palos Verdes Drive South right now, you aren’t just looking at a scenic coastal road; you’re looking at a multi-million dollar asphalt Band-Aid that gets reapplied almost every single week. It’s wild. The Palos Verdes landslide isn’t some new headline that popped up out of nowhere, but the sheer velocity of the movement over the last year has shocked even the geologists who have spent decades monitoring the area.
Basically, the earth is winning.
For years, the Portuguese Bend area moved maybe a few inches annually. It was a manageable, albeit expensive, quirk of living on one of the most beautiful peninsulas in California. Then the rains hit. The historic storms of 2023 and 2024 acted like a lubricant for ancient slip planes deep underground. Now? We are talking about feet, not inches. In some spots, the land is sliding toward the Pacific at a rate of seven or eight feet per year. You can’t just "fix" that with a retaining wall.
Why the Palos Verdes Landslide Won’t Stop
Geology is patient. The Palos Verdes Peninsula is essentially a giant layer cake of volcanic ash and sedimentary rock. Specifically, there's this stuff called Bentonite. When Bentonite gets wet, it turns into something resembling axle grease.
Imagine a heavy layer of rock sitting on a slide made of wet soap. That is the Portuguese Bend.
The ancient landslide complex was actually dormant for thousands of years until 1956. That’s when Los Angeles County started building an extension of Crenshaw Boulevard. They moved thousands of tons of dirt, placing it right on top of the prehistoric slide area. The added weight, combined with some poorly timed septic drainage from early homes, woke the giant up. It hasn't gone back to sleep since.
Honestly, the sheer physics of it are terrifying. The City of Rancho Palos Verdes has been fighting a war of attrition. They’ve installed hydraugers—basically giant horizontal straws—to suck water out from deep within the hillside. The logic is simple: if you keep the grease (the Bentonite) dry, the slide slows down. But when the sky opens up and dumps record-breaking rainfall, the hydraugers can’t keep up. The water saturates the layers, and the "grease" gets slick again.

The Human Cost: No Power, No Gas, No Warning
It’s easy to look at the photos of buckled roads and think, "Well, that sucks for those rich people." But it’s getting way more complicated than just property values. In late 2024 and early 2025, the situation turned from a slow-motion disaster into an active emergency.
Southern California Edison (SCE) finally had to pull the plug.
The ground was moving so fast that electrical poles were leaning at 20-degree angles. Transformers were blowing. Lines were snapping. It became a massive fire risk. For hundreds of residents in the Seaview and Portuguese Bend neighborhoods, the power just... went away. Permanently. Then SoCalGas cut the lines because the shifting earth was threatening to snap gas mains, which would have turned the entire hillside into a tinderbox.
Imagine living in a $3 million home with no electricity and no heat. Some people are running on massive Tesla Powerwalls and solar arrays, but even those systems struggle when the foundation of your house is literally cracking in half.
- Wayfarers Chapel: This is probably the most heartbreaking part for locals. The "Glass Church," designed by Lloyd Wright (Frank Lloyd Wright’s son), had to be meticulously disassembled. The landslide was literally pulling the structure apart. It’s gone for now, sitting in storage boxes until they can find a "stable" place to rebuild it.
- The "Ski Jump": That’s what locals call the warped sections of Palos Verdes Drive South. The city crews are out there constantly, leveling it with fresh asphalt so emergency vehicles can still pass.
- The Red Tags: Homes that have been there for fifty years are being declared uninhabitable in a matter of weeks.
The Misconception About "Fixing" the Peninsula
People keep asking why the state doesn't just build a bridge over the slide or "anchor" the rock.
You can't anchor something this big.

The Palos Verdes landslide involves millions of tons of earth moving toward the sea. It’s not a surface-level mudslide; it’s a deep-seated rotational slide. If you try to build a bridge, the supports for that bridge will move. If you try to drive pilings into the bedrock, you’ll find that the "bedrock" is actually part of the moving mass.
Geologist Elia Landa and others who study the Palos Verdes Fault and the surrounding complexes have noted that this isn't just one slide. It's a network. You have the Portuguese Bend slide, the Abalone Cove slide, and the Beach Club slide. They all interact. When one moves, it changes the pressure on the others. It’s a chaotic, geological domino effect.
The current strategy is "dewatering." The city has been drilling new extraction wells to pull water from the "shear zone" where the sliding actually happens. They are also trying to seal the cracks in the ground. When the ground cracks, rainwater flows directly into the slide plane. It's a vicious cycle. You have to fill the cracks to keep the water out, but the ground moves so fast that new cracks open up the next day.
Can Technology Save the Homes?
There is some talk about using massive "shear pins"—huge steel and concrete cylinders—to stitch the land together. It worked for some smaller slides in Malibu. But the scale here is totally different. The sheer volume of moving earth would likely just snap those pins like toothpicks.
The real talk in the halls of the state capitol is about "managed retreat."
It’s a fancy way of saying we might have to give up. The cost to maintain the infrastructure—water, power, sewage, and roads—is starting to outweigh the tax revenue from the area. It’s a brutal reality. Governor Newsom declared a State of Emergency for Rancho Palos Verdes, which opened up some funding, but that money is mostly for emergency stabilization, not for long-term "fixes" that might not even exist.

What You Need to Know If You Visit
Don't go there to gawp. Seriously.
If you’re planning to drive down to see the "sunken city" vibes, just know that the roads are genuinely dangerous. Palos Verdes Drive South can have a six-inch drop-off that wasn't there two hours ago. The city has installed "dip" signs and 10 mph speed limits, but the terrain changes constantly.
Also, the hiking trails? Most of the Portuguese Bend Reserve is closed or highly restricted. The land is unstable. A crack that looks like a small step could be the edge of a thirty-foot drop-off hidden by brush.
Actionable Steps for the Future
The Palos Verdes landslide is a case study in why we need to respect geological boundaries. If you are a homeowner in a hillside area or looking to buy in Southern California, there are some very real lessons to take away from this mess.
First, check the California Geological Survey (CGS) landslide maps. They aren't just suggestions. If a property is in a "high sensitivity" zone, your insurance will be a nightmare, or more likely, non-existent for earth movement. Most standard homeowners' insurance policies specifically exclude landslides. You need a separate "Difference in Conditions" (DIC) policy, and in Palos Verdes right now, those are nearly impossible to get.
Second, if you're an owner in a moving zone, focus on water management. Ensure your gutters are clear and discharging as far away from the foundation as possible. Inspect your property for "tension cracks"—linear cracks in the soil that run parallel to the slope. These are the first signs that the earth is starting to pull apart.
Third, stay informed on the city's dewatering efforts. The success of those deep wells is the only thing standing between the current slow slide and a catastrophic collapse. If the dewatering fails, the "managed retreat" of the entire Portuguese Bend community might move from a theoretical plan to an immediate requirement.
The situation in Palos Verdes is a reminder that the Earth is a living, moving thing. We like to think of "land" as permanent, but as the residents of Portuguese Bend are finding out, sometimes the land has other plans. Monitoring the GPS data from the city's sensors is the best way to see the real-time truth of the movement, which remains at record-breaking speeds as we head into another uncertain winter.
