Richard G. LaHusen William L. Ellis Mark E. Reid 1999 Landslides threaten lives and property in every State in the Nation. To reduce the risk from active landslides, the U.S. Geological Survey (USGS) develops and uses real-time landslide monitoring systems. Monitoring can detect early indications of rapid, catastrophic movement. Up-to-the-minute or real-time monitoring provides immediate notification of landslide activity, potentially saving lives and property. Continuous information from real-time monitoring also provides a better understanding of landslide behavior, enabling engineers to create more effective designs for halting landslide movement. application/pdf 10.3133/fs09199 en Geological Survey (U.S.) Real-Time Monitoring of Active Landslides reports
