PEER and Lawrence Berkeley National Laboratory (LBNL) will host an online workshop on the Simulated Ground Motion Database (SGMD), an open-access resource supporting research and engineering applications involving simulated earthquake ground motions. This workshop will bring together researchers and practitioners to share how SGMD is being used in practice, highlight recent applications, and gather feedback to inform future development. The event will also provide an opportunity to strengthen connections within the growing SGMD user community and encourage collaboration.
