In coastal Southern California, residents in an affluent community are dealing with devastating landslides that are threatening their homes.

30 miles south of Los Angeles, Rancho Palos Verdes has seen active but slow-moving landslides since the 1950s, but they've recently sped up, partly thanks to record amounts of rain in Southern California over the last two years.

Now, as roads buckle and homes lie partially swallowed by the ground, scientists warn landslides are set to become more frequent as the climate fuels heavier rainfall and more powerful storms.

It's as if the earth is wiping away what's been built upon it.

I'm no geologist, but when you see the road turning into a roller coaster, you know something's wrong.

Here in Rancho Palos Verdes, an affluent community coveted for its expansive Pacific Ocean vistas, the land is sliding dangerously.

This is unprecedented.

No one knows really in a way what to do.

While the land has always slowly shifted here, local leaders say it's accelerated tremendously.

Unbelievable, in the last four months, it's constant.
