Objective: This workshop intends to provide closer personal connections between NZ researchers, end-users and international collaborators on ground motion simulation through a mix of invited presentations and open floor discussion on research challenges and implementation issues.
QuakeCoRE’s ground motion simulation activities strive for in a paradigm shift in strong ground motion prediction through the use of high-fidelity physics-based simulation methods; merging state-of- the-art knowledge in strong motion seismology and geotechnical earthquake engineering; validating simulations via application to advanced numerical models of engineering infrastructure; and developing guidance for the use of such simulation methods in engineering design and assessment.
