Landslide Monitoring

Monitoring is essential to predicting the behavior of landslides and forecasting which storms can trigger large numbers of landslides. Scientists in the USGS Landslide Hazards Program monitor selected landslides and hillsides in order to learn more about the physical processes that trigger landslides or control their movement.

Current Monitoring Sites

(Click a site's marker for more information.)

Continuous, real-time monitoring occurs at some sites and periodic monitoring occurs at others; the most recent measurements are provided on-line for a few of our monitoring sites.

Graphs showing the most recent data are updated regularly with update cycles ranging from 15 minutes to 24 hours. Landslide monitoring data and information provided on this web site are preliminary and have not been reviewed for accuracy; therefore the data are subject to revision.
