🌍 Structural Dynamics & Earthquakes

Free data, maps and programs for vibrations and earthquake engineering: where the ground shakes, how strong, real earthquake records and the tools to process them. Analysis programs like OpenSees and Frame3DD are in Structural Analysis; the background is in my note Structural Dynamics and Earthquakes.

European Seismic Risk Model (ESRM20)
maps.eu-risk.eucentre.it
Interactive maps of the expected damage and losses from earthquakes in Europe, by region – the step from "how strong is the shaking" to "what happens to the buildings".
