Geodynamic hazard and risk assessments for sites close or in tectonic zones with shear movements

No region is excluded from actions of recent geodynamic short- or long-term effects which can be observed even on the Earth’s surface. The article delivers a geodynamic hazard assessment for the anthropogenic objects threatened by permanent shear movements occurring along tectonic faults and a way how to mitigate and/or eliminate the object risk. The proposed approach is applied to a case example of a motorway tunnel leading through rock masses where dynamically active zones with shear movements along their faults are expected. To detect the shear movements among rock masses, the contemporary satellite geodetic GPS methodology was used.
