66 KB (Updated 11-8-2010)

This Geographic Information System (GIS) point shapefile of Landslides in New Jersey with associated database file, projection file and metadata, contains point locations and other attributes for 181 landslide locations in New Jersey mapped by the New Jersey Geological Survey (NJGS). The landslides have occured in the northern and central part of the state and include slumps, debris flows, rockfalls and rockslides. Although in New Jersey landslides are not as common as in other areas of the United States, they are a geologic hazard in areas with steep to moderate slopes or geologic units prone to failure. They cause damage to utilities, property, and transportation routes. The average annual direct and indirect cost of New Jersey landslides is likely in the hundreds of thousands of dollars. New Jersey landslides have also caused fatalities and injuries. The landslides are caused by heavy rains, weathering, ocean waves, quarrying and construction activites.
