Seismic Techniques for Natural Hazard Investigations

Traditional methods for characterizing and monitoring slope instabilities often rely on sensing surface displacements, potentially missing critical subsurface changes. Ambient seismic vibration techniques provide a solution by revealing important information about the structural properties of rocks and soils. These techniques allow mapping and characterization of instabilities and assessment of material degradation independent of surface deformation, and can even be used for real-time monitoring.

«Our mission is to bring the latest developments in ambient seismic vibration techniques and engineering geophysics, with a special focus on natural hazards, into practical applications.»
