In regions where earthquakes are common, buildings are repeatedly exposed to ground motions (GMs) of varying intensity. These motions come from earthquakes on well‑mapped regional faults as well as from sources that may not yet be identified. Seismic hazard analysis (SHA) is the discipline devoted to estimating how often, i.e. the annual rate, a site…
Sand Box: Hazard Analysis for Earthquakes on Virtual Faults In seismically active regions, buildings will experience different ground motions (GMs) intensities from earthquakes on different regional seismic sources. Seismic hazard analysis (SHA) quantifies the expected average annual frequencies for a site or building to experience ground motions higher than different assumed levels. Significant uncertainties exist…

The primary objective of this platform is to provide rigorous technical insight into the analytical foundations of earthquake hazard formulation. Designed for researchers and practitioners, this site bypasses introductory overviews to focus directly on complex numerical models, hazard formulation, and interactive data visualization. Rather than processing large-scale, generalized datasets, this environment is optimized for focused,…
