LOS ANGELES (KTLA) – New research from NASA shows that the Palos Verdes Peninsula, an area in the South Bay and home to cities like Rancho Palos Verdes, Rolling Hills Estates and San Pedro, is shifting toward the ocean.

Data from NASA’s Jet Propulsion Laboratory airborne radar shows that during a four-week period last fall, the residential area shifted toward the Pacific Ocean as much as 4 inches per week.
