Structure, Mechanics, and Hazards of Geometrically Complex Fault Systems

Session ID#: 158573

Session Description:
Across many tectonic settings, major active fault systems commonly consist of multiple intersecting or neighboring faults. High-resolution observations from recent large earthquakes show that these events often rupture multiple fault segments and generate significant off-fault damage. Over a wide range of timescales, details of the mechanical interactions between segments in complex fault systems remain challenging to untangle. Nonetheless, these interactions appear to influence the seismic and tsunami hazards resulting from complex earthquake ruptures. This session will focus on new observations and models that illuminate how complex fault systems form and deform over geologic to coseismic timescales, and how complex faulting affects natural hazards for nearby communities. Submissions are encouraged from a broad range of disciplines including geology, geomorphology, seismology, geodesy, rock mechanics, and geodynamics, among others.
