T42A:
Earthquake Recurrence Patterns and Spatiotemporal Variations of Strain Release Along Faults

Submit an Abstract to this Session



Session ID#: 34918

Session Description:
This session aims to discuss the temporal and spatial recurrence patterns of slip along faults accumulated over multiple seismic events. Whether fault slip accumulation follows a ‘characteristic’ pattern with similar magnitude and distribution in successive events, or is more heterogenous (i.e., the ‘variable-slip’ model), has been an open question. The temporal recurrence patterns of events seen in the geologic record also shows a range of behaviors, with some faults exhibiting clustering and others quasi-periodicity. Recent improvements in various geochronologic dating techniques, and measurements of offset geomorphic features from high-resolution topography, can help constrain slip histories and the appropriate recurrence model. Additionally, earthquake simulators and analogue experiments give useful clues into the longer-term behavior of strain release, such as fault evolution and interaction. We encourage submissions which use paleoseismology, geomorphology, earthquake cycle simulations and analogue experiments to explore the patterns and physical mechanisms behind spatiotemporal variations of strain release along faults.
