T43C:
Diversity of Fault Slip Modes and the Interplay between Seismic and Aseismic Behavior of Faults: Insights from Geodesy, Geology, and Rock Mechanics I Posters


Session ID#: 7846

Session Description:
Recent geodetic and seismological observations have highlighted the variety of seismic and aseismic slip behavior along active faults in the shallow crust. Recent techniques, including InSAR and GPS, allow quantification of the broad range of slip rates at all spatial and temporal scales. Analysis of these modes of slip has led to a preliminary mechanical description of active faults. We welcome contributions combining geodetic, seismic, geologic and/or laboratory-derived observations to explore the mechanical processes leading to this variety of slip behaviors.

What is the spatial and temporal distribution of fault slip in various tectonic settings? How stable is the partitioning between seismic and aseismic slip? Can geodetic and geological measurements of slip help us quantify fault properties and assess their temporal stability? How are these effective properties related to field observations of deformation mechanisms? What are the consequences for our understanding of the interplay between seismic and aseismic slip?
