The Palos Verdes Peninsula in Los Angeles County, California, is sliding toward the Pacific Ocean at a rate of four inches per week, according to recent data from NASA’s Jet Propulsion Laboratory. This alarming movement was observed over a four-week period last fall, highlighting the risks to human life and infrastructure in the area.
The Palos Verdes Peninsula, home to cities such as Rancho Palos Verdes, Rolling Hills Estates, and San Pedro, has long been prone to landslides. However, the situation worsened after Hurricane Hilary’s record-breaking rainfall in 2023, which accelerated the land movement. As a result, significant damage has occurred, including the indefinite closure of the Wayfarers Chapel in Rancho Palos Verdes and the buckling of roadways. Some homeowners have been offered buyouts for properties threatened by the shifting ground.
NASA’s airborne radar data revealed the extent of the movement, with darker red areas indicating faster motion. The analysis by NASA scientist Alexander Handwerger emphasized the expanded footprint of land experiencing significant impacts.
Governor Gavin Newsom declared a state of emergency in the area last year due to the ongoing land movement. As the situation develops, residents and officials continue to grapple with the challenges posed by the shifting landscape.
