T23D:
Bridging Tectonics and Earthquake Cycles IV

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 16023

Session Description:
Long-term tectonic processes shape the bulk of conditions under which faults operate and thereby influence earthquake processes on short time scales. In turn, rupture processes locally reduce the strength of the brittle lithosphere and thereby affect long-term processes. Reconciling observations of mechanisms taking place across these different time and spatial scales will improve our understanding of the rheology of the lithosphere-asthenosphere system and may ultimately improve seismic hazard assessment. What are the driving forces and the rheological structure at plate boundaries? What are the relative contributions of rheology (temperature, fluids, chemistry) and geometry in the segmentation of fault ruptures? What are the roles of faulting and off-fault deformation in shaping the landscape and partitioning seismic and aseismic energy dissipation? We seek contributions from across the fields of geology, geodynamics, seismology, and geodesy  involving both modelling and observational studies.
