Effects and costs of landslides in pennsylvania urban and rural land development is increasing both the number of landslides and the economic effects of natural slides major highway construction with large excavations and fills located in mountainous areas creates the potential for many landslides. The landslide ultimately reached 1000 feet in width, nearly 200 feet in thickness, and over one mile in length the lower end of the slide formed a 220-foot-high dam where it abutted against a sandstone cliff at the base of billies mountain.
The term landslide includes a wide variety of mass movements that result in the downward and outward movement of slope forming materials like rocks, soils, artificial fills or any combination of these, under the influence of gravity it is a geographical phenomenon, including wide range of ground movement, when the shear stress exceeds the shear strength of the materials. Landslides often have devastating effects on humans the wall of mud wipes out buildings, covers roads and changes the landscape the economic cost of landslides in the united states ranges from $1 billion to $2 billion annually.
