This open access book highlights the latest advances, innovations, and applications in the field of earthquake engineering, as presented by leading international researchers and engineers at the International Workshop in Engineering Research Infrastructures for European Synergies (ERIES-IW), held in Lisbon, Portugal, on May 7-9, 2025. The event was meant to provide a unique platform to exchange experiences, share results, and explore future directions in seismic, wind, and geotechnical engineering research, with a focus on reducing hazard-related losses, managing risk, and fostering sustainable solutions. The contributions, which were selected by means of a rigorous international peer-review process, present a wealth of exciting ideas that will open novel research directions and foster multidisciplinary collaboration among different specialists. .
