Fault deformation during the seismic cycle: from the field to the laboratory

Session ID#: 76380

Session Description:
Strong feedbacks exist between fault behavior, and rocks of the fault core and damage zone. Coseismic fault rupture propagation results in an increase in fractures in the damage zone. An immediate feedback occurs via (fracture) energy consumption and the potential triggering of different dynamic weakening mechanisms (i.e. thermal pressurization vs frictional melting) due to modifications of the thermal and hydraulic properties of the damage zone. An increase of permeability and porosity in the damage zone would influence post- and interseismic processes and allow for large-scale co- and interseismic fluid movement along the fault zone that affects fault healing and stress recovery.  

We welcome studies of rock-deformation experiments, field investigations, seismology and numerical modelling that investigate, i) mechanical, chemical and hydrological processes on seismic or aseismic faults, ii) feedbacks that arise between different fault zone processes during inter- and co-seismic periods, and, iii) the effects of structural heterogeneity on fault properties.
