Interplay between Seismic and Aseismic Slip on Seismogenic Faults

Session ID#: 85447

Session Description:
Tectonic faults accommodate plate motion through various styles of seismic and aseismic slip spanning a wide range of spatiotemporal scales. Understanding the mechanics and interplay between seismic rupture and aseismic slip is central to seismotectonics as it determines the seismic potential of faults. In particular, unraveling the underlying physics controlling these styles of deformation bears a great deal in earthquakes hazards mitigation especially in highly urbanized regions. We invite contributions from observational, experimental, geological and theoretical studies that explore the diversity and interplay among seismic and aseismic slip phenomena in various tectonic settings, including the following questions: (1) How does the nature of creeping faults change with the style of faulting, loading rate, and other factors? (2) Are different slip behaviors well separated in space, or can the same fault areas experience different failure modes? (3) Is there a systematic spatial or temporal relation between different types of slip?
