This volume collects several extended articles from the first workshop on Best Practices in
Physics-based Fault Rupture Models for Seismic Hazard Assessment of Nuclear Installations
(BestPSHANI). Held in 2015 the workshop was organized by the IAEA to disseminate the use of
physics-based fault-rupture models for ground motion prediction in seismic hazard assessments
(SHA). The book also presents a number of new contributions on topics ranging from the
seismological aspects of earthquake cycle simulations for source scaling evaluation seismic
source characterization source inversion and physics-based ground motion modeling to
engineering applications of simulated ground motion for the analysis of seismic response of
structures. Further it includes papers describing current practices for assessing seismic
hazard in terms of nuclear safety in low seismicity areas and proposals for physics-based
hazard assessment for critical structures near large earthquakes. The papers validate and
verify the models by comparing synthetic results with observed data and empirical models. The
book is a valuable resource for scientists engineers students and practitioners involved in
all aspects of SHA.
