A detailed field mapping of spatial geometries of the surface coseismic ruptures of active faults is the basis for the identification of seismogenic structures. Field mapping of fracture distributions, fault offset, and links between geometries along the fault strands are the essential tools for extrapolating and constraining the depth of the fault plane from a kinematic point of view. These geometries can be expressed as orientations derived from strike and dip values collected during a structural survey, in which the kinematic fault analysis are integrated with geophysical data, allowing to constrain any seismogenetic model. Integration of geological and seismological data remains one of the main objectives when identifying active faults and assessing their potential hazard.
