The Sunken City is the site of a natural landslide which occurred in the Point Fermin area of the San Pedro neighbourhood of Los Angeles, starting in 1929. A slump caused several beachside homes to slide into the ocean. The development of cliffside homes and exclusive bungalows was established in the 1920s by George H. Peck to attract people who wanted to live with a view of the Pacific Ocean. Experts investigating the landslide said that the ground was shifting at a rate of 11 inches per day.
