Get Prototype Landslide Hazard Map Of The Conterminous United States - Profile Usgs

Landslide hazard areas are lands that are subject to mass earth movement due to a combination of geologic, topographic, and hydrologic factors with a vertical height of 10 feet or more.

Landslide Warning Signs Springs, seeps, or saturated ground in areas that have not typically been wet before. New cracks or unusual bulges in the ground, street pavements or sidewalks. Soil moving away from foundations. Ancillary structures such as decks and patios tilting and/or moving relative to the main house.

These maps might be as simple as a map that uses the locations of old landslides to indicate potential instability, or as complex as a map incorporating probabilities based on variables such as rainfall, slope angle, soil type, and levels of earthquake shaking.

The primary objective of the National Landslide Hazards Program is to reduce long-term losses from landslide hazards by improving our understanding of the causes of ground failure and suggesting mitigation strategies.

It can be used as a tool to help identify land areas best suited for development by examining the potential risk of landsliding. Furthermore, once landslide susceptibility is identified, investment projects can be developed which avoid, prevent, or substantially mitigate the hazard.

The U.S. Geological Survey is the nation's largest water, earth, and biological science and civilian mapping agency. It collects, monitors, analyzes, and provides scientific understanding of natural resource conditions, issues, and problems.

Landslide monitoring involves the usage of a durable prediction and forewarning system, coupled with effective efforts to curb the slope movement. The destruction can be drastically reduced with the help of monitoring and instrumentation.
