Probabilistic Seismic Hazard Analysis (PSHA) provides a modelling platform that connects developments in seismic sources, ground motions and risk analysis within an engineering-oriented application framework. This session welcomes contributions on best and emerging practices in modelling and implementing seismic sources and ground motions in PSHA; consideration of time-dependent hazards including induced seismicity; developments in site-specific, regional and national seismic hazard models, including partially and fully non-ergodic approaches; treatment of multi-hazards (e.g. earthquake; tsunami); and risk and resilience. The session aims to bring together researchers and practitioners working from local to regional to national scales on quantitative hazard assessment and practical approaches to risk reduction.
