T51A:
Characterizing Fault Zones in Space, Time, Temperature, and Texture I Posters


Session ID#: 9167

Session Description:
The geometrical character and mechanical properties of active fault zones exert a strong influence on earthquake rupture and seismic wave propagation. Measurements of damage zone distribution, fault geometry, seismic velocity, fault friction, fluid flow and rheology inform rupture directivity, ground motion and the likelihood of segment linkage during large events. Constraining these properties, including their depth variation, is crucial to an accurate understanding of the hazard posed by active faults. Recent advances in field surveys, terrestrial and aerial LiDAR, seismic noise correlation and seismic tomography, InSAR, and cross-correlation of optical imagery provide unprecedented spatial resolution for measurement of fault zone properties. We seek multi-disciplinary contributions including field, seismic and geodetic studies that provide constraints on the physical properties of active fault zones from the surface through the seismogenic zone.
