Data gathered from four weeks in the fall of 2024 showed the speed of the movement to be "more than enough to put human life and infrastructure at risk," Alexander Handwerger, JPL landslide scientist said.

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

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.
