The USGS Landslide Hazards Program conducts research in order to make accurate landslide hazard maps and forecasts of landslide occurrences by answering these major questions: Where and when will landslides occur? How big will the landslides be? How fast and how far will they move? What areas will the landslides affect or damage? How frequently do landslides occur in a given locality?
