T42C:
Interplay Between Seismic and Aseismic Slip: Implications for Fault Physics II


Submit an Abstract to this Session


Session ID#: 57008

Session Description:
Faults at tectonic boundaries accommodate plate motion through an array of seismic and aseismic modes of deformation. Even within these categories, there are important differences among event slip characteristics. For example, earthquakes exhibit variations in their frequency content and tsunamigenic potential. Aseismic slip transients are often, but not always, accompanied by tectonic tremor, and there remains much to be understood about the relationship between aseismic transients and earthquake nucleation. We invite contributions from observational, experimental, geological and theoretical studies that explore the variations in and interplay among seismic and aseismic slip phenomena in various tectonic settings, including the following questions: (1) Are different slip behaviors well separated in space, or can the same fault areas experience different failure modes? (2) Is there a systematic spatial or temporal relation between different slip types? (3) What are the physical mechanisms that govern this complex behavior?
