Scenario-Based Seismic Hazard Assessment

Abstract: For historical buildings and monuments, and for relevant engineering purposes, a viable alternative to standard estimates of seismic hazard is represented by the use of the scenario earthquakes, characterized at least in terms of magnitude, distance and faulting style, also taking into account the complexity of the source rupturing process. Scenario-based NDSHA seismic input naturally supplies realistic time series of ground motion, readily applicable to engineering analysis. This methodology has been successfully applied to many urban areas worldwide for the purpose of seismic microzoning, to strategic buildings, lifelines and cultural heritage sites, and some examples will be discussed. The lecture attendees will receive lecture notes.
