Combined Use of DAS and DSS for Landslide Detection and Assessment

Summary A variety of landslides such as mud flow, rock fall and rock avalanche can be detected with Distributed Acoustic Sensing (DAS). The consequences of the event and the preliminary signs of its development can be assessed by Distributed Strain Sensing. The combination of DAS and DSS instrumentation in the Geotechnical Monitoring System (GTMS) helps to mitigate geohazard risks along infrastructures crossing challenging environments.
