Seismic hazard analysis (SHA) has become the basis for urban planning and earthquake-resistant design of both onshore and offshore structures. GEAmb applies a probabilistic approach that accounts for uncertainties in both data and mathematical models, thus allowing the quantification of the degree of confidence in the proposed solutions.

GEAmb’s services in this field include:

• Compilation of earthquake catalogues and seismotectonic studies
• Characterization of earthquake sources (i.e., faults) and definition of seismogenic zonations
• Logic tree probabilistic seismic hazard analysis (PSHA) and hazard deaggregation
• Definition of seismic input (i.e., suite of earthquake time histories) for dynamic analyses
