Monetary losses from landslides come from the destruction of infrastructure, homes and businesses; loss of life; disruption of transportation routes; disruption and contamination of water supplies; and the difficulty of both removing and stabilizing landslide material. Even a small landslide that damages a few homes can cost millions of dollars. Losses from landslides in the United States were estimated in 1980 to exceed $1 billion per year. More recently, the U.S. Geological Survey estimated annual losses to be between $2 billion and $4 billion per year. However, landslide costs across the country are not currently tracked or measured in a uniform way by any one agency, so this figure is likely to be an underestimate.
