CONVENERS: Sanaz Rezaeian, Nicolas Luco, Brendon Bradley, Iunio Iervolino, and Leonardo Ramirez-Guzman

OVERVIEW: Established in 2011, the SCEC Ground Motion Simulation Validation (GMSV) Technical Activity Group (TAG) is focused on developing and implementing, via collaboration between ground motion modelers and engineering users, testing/rating methodologies for simulated ground motions that are to be used in engineering applications. In the past year, for example, the GMSV TAG has implemented a gauntlet of validation tests on the SCEC Broadband Platform, a software system that can simulate 0-100 Hz seismograms using several alternative computational methods. Meanwhile, a national network of leading New Zealand Earthquake Resilience Researchers, QuakeCoRE, has begun research there on ground motion simulation and validation, including collaboration with practicing engineers on a document entitled “Guidance on the utilization of earthquake-induced ground motion simulations in engineering practice.” In Italy, a consortium of earthquake engineering laboratories known as ReLUIS has been working on regional simulation of earthquake events and their validation via models of buildings that have suffered damage in corresponding historical events.

This workshop will summarize these international GMSV efforts and possibly others, further coordinate them, and initiate future collaborations. The main goal of the workshop is to discuss the future of the GMSV TAG in SCEC5. We will encourage discussions on 1) the organization and structure of the TAG based on lessons learned from other international groups, focused on encouraging interactions between validation researchers, simulation modelers and end users, 2) the need for developing a database interface, where users can access the SCEC simulated earthquake ground motions, and 3) engagement with engineering users and outreach by moving towards an integrated earthquake ground motion simulation and validation program that builds on the knowledge from previous independently-funded GMSV TAG projects. Thus, the workshop will be of interest to ground motion modelers, engineering users, and international delegates alike.
