The land under the Palos Verdes Peninsula has been sliding for decades. New data from NASA shows just how bad the problem is.

The Palos Verdes Peninsula is well-known for its landslides, which have been occurring for decades. But radar imagery recently revealed that the Los Angeles County community is experiencing a slow-moving landslide -- averaging about 4 inches per week between Sept. 18 and Oct. 17, 2024, NASA's Jet Propulsion Laboratory found.

The peninsula is home to Rancho Palos Verdes, which faced sweeping power shutoffs last year due to land movement.
