Landslides are one of the costliest natural hazards worldwide. Recent advances in geophysical techniques are facilitating increasingly detailed studies of landslide subsurface features and processes. Combined with in-situ geotechnical and hydrological sensors, surface and remotely sensed geophysical data are beginning to be integrated into early-warning systems, reducing landslide risk to vulnerable communities, and are employed to inform pro-active remediation measures by elucidating hydrological precursors to failure. This is particularly important as hydrological processes in unstable slopes are known to be highly variable both spatially and temporally. Characterizing and monitoring landslides using geophysical methods still faces challenges, such as accounting for sensor movements and capturing dynamic processes in heterogeneous ground. We invite observational and modelling studies that demonstrate novel geophysical approaches to investigating landslides. We encourage submissions on landslide characterization and monitoring, linking of geophysical data with hydrological/geomechanical modelling, and the integration of geophysical techniques into early-warning systems.
