The Ground-Shaking Intensity Model Service (eGSIM) is part of the European Facilities for Earthquake Hazard and Risk (EFEHR), a non-profit network of organisations and community resources aimed at advancing earthquake hazard and risk assessment in the European-Mediterranean area.

eGSIM is a web application programming interface (API), implemented along the lines of popular seismological web services (e.g., FDSN): the user can perform queries via configurable URLs in order to retrieve model predictions of ground motions from either observed or hypothetical earthquake scenarios. These can be used to develop model-to-model comparisons of the expected shaking, but also to provide fields of expected ground motions and their uncertainties at user-defined locations.

This portal is eGSIM Graphical User Interface (GUI) allowing users to:

With eGSIM we also foster the future development of tools to visualize and compute ground-shaking fields (“shake-maps”) taking into account fault finiteness, spatial correlations of ground-shaking and definition of spatially variable amplification factors, and to explore the components of variability in predicted earthquake ground motions in order to retrieve region-, source- ("between-event term") and site-specific properties of strong motion scaling (stations "site-term")

We welcome feedback on eGSIM. Please open an Issue in the GitHub Repository with the desired label (e.g. bug, enhancement, question, help)
