Liquefaction Susceptibility. landslide is a mass of rock, soil and debris displaced down slope by sliding, flowing or falling (mudflows, or "mudslides" are types of landslides). Landslides can be a direct result of an earthquake, as occurred in Daly City during earthquakes in 1906, 1957, and 1989.Betsy Malloy Photography. The San Andreas Fault begins near the Salton Sea, runs north along the San Bernardino Mountains, crosses Cajon Pass, and then runs along the San Gabriel Mountains east of Los Angeles.
