The Nature of Creeping Faults: Where, Why, and How They Slip Slowly II Posters


Submit an Abstract to this Session


Session ID#: 45451

Session Description:
Fault creep has been observed worldwide in continental regions as well as on many subduction thrusts. With improved resolution of fault kinematics using dense geodetic and seismologic data, the spatial distribution of fault creep has been intensively investigated on a variety of faults. In rock mechanics experiments, the frictional behavior of fault materials has been studied to better understand what enables a fault to creep. How much do we know about the similarities and differences between shallow creep (upper few km) and deep creep (>10 km deep) from microstructures, mineral composition, lithologic properties and conditions, geodesy, and geophysical methods? How well can we define zones of aseismic slip through integrated data? The goal of this session is to bring together different disciplines for improving our understanding on why and how faults creep. We encourage multi-disciplinary contributions from geological, geophysical, experimental, and modeling studies of creeping faults.
