S41D:
Beyond the Earthquake Cycle: Field and Modeling Constraints of Earthquake Rupture Along Complex-Geometry Fault Systems and Implications for Seismic Hazard Assessment Posters


Submit an Abstract to this Session


Session ID#: 48938

Session Description:
Current seismic hazard assessment (SHA) relies on seismotectonic proxies and regional seismicity to estimate possible future earthquakes' shaking levels. Because the observational time span is too short to capture a fault'€™s seismic cycle, many important SHA-quantities are ill-defined (e.g. earthquake occurrence rate, maximum magnitude). The only way to provide more reliable earthquake rupture forecasts and to explore realistic earthquake behaviors is to integrate observations from earthquake geology with advanced seismic-cycle and dynamic earthquake rupture simulations. This session will bring together scientists from respective fields, with focus on the state-of-the-art understanding of earthquake rupture along complex fault systems. We encourage contributions from earthquake geology that constrain fault behavior and rupture characteristics of past earthquakes, including slip-rate estimates, along-fault slip accumulation, earthquake recurrence characteristics. We also seek abstracts addressing rupture along complex-geometry fault systems through dynamic and multi-cycle rupture simulations. Contributions addressing incorporation of fault-based rupture characteristics into SHA studies are welcome.
