Experts believe entire Palos Verdes Peninsula may be at risk after recent landslide

Are you telling me if you build a building on a cliff it may slide off? Unbelievable

That man is getting upset saying "there should have been more warning." Of course, blame someone else but he bought a house built on the side of a giant ravine!

I'm from CA, and I have always thought as a kid that it's stupid to build homes on hills like this.

I grew up in Southern California and it's been well known for many, many years how dicey and unstable these areas are. Why they allowed all these neighborhoods to be built up is beyond me.

Why were developers allowed to build there in the first place?

The Palos Verdes fault line runs directly underneath the Palos Verdes Peninsula, and though mostly underwater, it sits under places like Rancho Palos Verdes, Rolling Hills Estates and the Long Beach and Los Angeles Harbors. The nearly 70 mile line stretches from Dana Point to the Santa Monica Bay.

Omg!! I never thought I’d see my geology professor from ten years ago on the news. Funny enough, I took “natural disasters” with him and we took a field trip to Portuguese Point to observe the massive risks related to land movement.

We have the same sort of issue on the Jersey shore. People built in flood prone areas near the ocean, and are then shocked when a hurricane floods everything and wipes out their homes...

People who lived in Palo Verde 50 years ago told me that the big disadvantage is that the land is unstable. It's not like this was unknown. It's not 'fixable'.

I lived in the South Bay area where Palos Verdes peninsula is located. I worked and played in Palos Verdes and Rolling Hills for many years. I dated a woman that lived in Palos Verdes Estates. Her pool was cracked in some locations. The lands up there are always moving. Portugese Bend has experienced landslides for many decades. It's an extremely beautiful place to live with views of the Pacific Ocean in some locations. But, i always wondered why building permits were issued in many places on the peninsula and why buyers of these homes were so damn naive. Do your homework, people.

In 1960, my parents were house hunting and looked at a home on Palos Verdes. I remember the view of being surrounded by nothing but ocean. It was beyond breathtaking. I was like "Dad! Get this house!" My dad said, "I'm not going to pay $23,000 for a house!"

Anyone who has driven around Portuguese bend knows the road area that is constantly moving. Its POSTED as 5MPH in some areas because of road buckling and shifting. That's been going on for decades. Nice views of Catalina on a clear day but very risky to build a property on.

The locals are all aware that RPV is built on unstable ground. There is even one road, "Portugese Bend" that has signs posted reminding drivers the ground there is in constant motion and not to stop their cars. The road itself is very bumpy and uneven, and utility pipes are laid above ground because they can't be buried in that soil. This is not new news to the local residents. It's a risk they took but they were not uninformed.

Hilltop homes are wonderful, but I chose not to purchase one in another area because I was afraid of earthquake damage or total destruction of a home perched on a hill. And with increased rainfall and atmospheric rivers these hills will slide more often. It is part of the geological and weathering processes.

I remember in the late 60’s (I was very young) riding by bike along PV Dr. South & the road was very unstable at that time. Clearly the road showed signs of a LOT of movement. We would stop and look out into the ocean and you could see this brown cloud in the water, which was part of the eroding hillside, hitting the water.

My parents told me about the collapse back in the early '60s in Rolling Hils and Palos Verdes. This has been an ongoing issue for over half a century, yet they continue to build in that area. At some point, you cannot be stupid anymore..

My friend is a geologist, and she says that developers never read the reports about the findings of whatever area they are trying to build on.. that’s terrifying!!

Sorry to ALL affected. They do call them "rolling hills" for a reason! Its a geological process and doesn't stop for home owners.

We once went house shopping in that area. One day we stopped at a listed unit. I got out of the car and looked over the gate at the side of the house. I felt like I was looking straight down the ravine at little roofs far below. I got a little dizzy. — We live in flat ol’ Torrance, now.

Almost 20 years ago, I used to jog through subdivisions and public areas to reach the Pacific coast in the south side of the peninsula. I remember (countless of times) how I could see new cracks forming week after week in the summer on Palos Verdes Blvd, some of them requiring shutting down traffic for the road crews to fix the problem. I also remember a lot for sale on a hill nearby Del Cerro park that literally “vanished” after a heavy rain (due to the landslide that followed). And some folks still pay millions for a house that may not last the next rainy season…
