An analysis by NASA’s Jet Propulsion Laboratory has determined that during a four-week period in fall 2024, land in some areas of Rancho Palos Verdes’ landslide area slid toward the ocean by as much as 4 inches per week.

The Palos Verdes Peninsula in Los Angeles County continues to inch toward the ocean posing danger to life and infrastructure, a NASA report found.

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

The residential area shifted toward the Pacific Ocean as much as 4 inches — per week — during a four-week period last fall.
