Landslides and Debris Flows in the California Central Coast Region
Landslides are a characterized as the falling or movement of soil or rock down a slope and can manifest through mudflows, mudslides, debris flows, rock falls, rockslides, debris avalanches, debris slides, and slump-earth flows. This movement occurs when the down-slope force exceeds the strength of the soil or other material holding the slope together. Typically, landslides take time to initiate movement as the soil saturates and ultimately moves at a slow pace, but can cause significant damage to buildings and other infrastructure.  Debris flows, a type of landslide, occur suddenly with shorter and intense rainfall creating a slurry that moves at a rapid pace and often can result in loss of life making them more dangerous.
In the United States, landslides are an extremely destructive hazard. Landslides in the country cause approximately $3.5 billion in damage, and kill between 25 and 50 people annually. On a more local scale, landslides are one of the most costly geologic hazards in Monterey County, costing millions of dollars yearly in infrastructure.
