The definition of a landslide is: A gravity driven down slope movement of a mass composed of soil, rock, and vegetation. A landslide generally happens when the material in the down slope is heavier then the supporting soil. There are many contributing factors that cause landslides, steepness of slope, composition of soil and rock, groundwater condition, recent precipitation patterns, slope aspects vegetation on slopes, and anthropomorphic activities (land clearing).

The rapid development of coastal areas and areas prone to landslides has increased the areas vulnerability to landslides.
Landslides are known to typically damage roads, railroads, sewer lines, water lines and homes, but that list should also include public buildings. Landslides are known for being detrimental to utilities because the force behind them can take down power lines like they are made of twigs. Even “small” landslides can be expensive. Clean up costs include but are not limited to, the clearing of minor to major debris, renewing and/or replacing the supports for bridges and roads and railroad embankments. Damages from these disasters include but are not limited to minor vehicle damages, minor to major building damage, personal injury up to and including death, and as mentioned before, loss of important
