Geotechnical hazard representation for seismic risk analysis
This paper focuses on the importance of an appropriate geotechnical hazard representation within a seismic risk analysis process. Seismic risk analysis, either deterministic or probabilistic, along with the use of a GIS environment to represent the results, are helpful tools to support decision making for planning and prioritizing seismic risk management strategies.
Within a framework for seismic risk analysis, different formulations would thus derive depending on both the intensity measure and the vulnerability approach adopted. In conclusion, an immediate visualization of the importance of the geotechnical hazard evaluation within a seismic risk analysis is provided in terms of the variation of the expected damage and consequence distribution with reference to a case-study.
