@knittingknots2 This California coast landslide is not a new problem, nor is it one that is at all likely to be resolved by somehow stabilizing the slope to protect the homes involved. It is sort of analogous to owning a mobile home built on former wetlands in Fort Meyers, FL. The desire to live near the ocean is strong and greed fuels development. Disasters are not "beyond what anyone could have foretold." ass the Mayor would have us believe. "The Portuguese Bend landslide, in coastal southern California, is an active, slow-moving mass of blocks and debris that extends from the shoreline to moderate altitudes along part of the southerly margin of the Palos Verdes Hills." "It evidently began in mid- to late-Pleistocene time, and it has continued intermittently to the present." https://www.sciencedirect.com/science/article/abs/pii/0013795289900379
