Seismic vulnerability, Caspian Sea southern coast

Seismic vulnerability degree evaluation is the main target in this research. Through correlation between earthquake focal points and the alignment of all faults using a geographical information system, the main active faults were distinguished. Recognition of the potential for earthquakes with Richter magnitude more than 5, seismic vulnerability was recognized. Combining all data layers, the geotechnical hazard potential was computed using a universal ranking system model (URSM). The main results show that recognition of active faults can improve seismic vulnerability degree and geotechnical instability assessment in this region.
