Abstract

Lessons learned from several case studies of deep-seated rockslides in foliated metamorphic rocks in Tyrol (Austria) are presented. Based on surface and subsurface investigations as well as monitoring and modelling campaigns the main topics are the geometry, structure, kinematics, hydrogeology and geomechanics of deep-seated rockslides. Experience was gained from geological field surveys, monitoring campaigns based on remote sensing and classical geodetic methods, sub-surface investigations by core drillings and drifts, geophysical methods and numerical modelling studies. These insights may help to understand the processes and mechanisms of case studies in similar geological situations where comprehensive investigations are not feasible or new investigation campaigns should be planned.
