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.

A coastal community in Southern California is shifting downslope toward the Pacific Ocean at a rapid rate, according to NASA.
