T043:
The Influence of Fault Zone Structure on Plate Boundary Tectonics and Earthquakes





Session ID#: 26243

Session Description:
This session seeks to highlight studies of fault zone properties in relation to transient slip, triggering, and rupture propagation direction across plate boundaries. Probabilistic-hazard source models may overestimate expected earthquakes in California. Paleoseismic and historical data in southern California indicate a 160 year long hiatus in great earthquakes. Factors affecting hazard model performance can include insufficient characterization of transient slip, slip triggering, and fault zone damage properties. These factors may arise in part because the crust is not purely elastic, and compliant material can serve to relieve stress aseismically. Differences in seismic velocities within the crust and fault geometry can control rupture propagation direction and whether earthquakes jump from one segment to another, cascading into larger events. This session encourages results based on geodetic, geologic, and seismic data that illuminate spatial and temporal patterns connecting fault zones with plate boundary deformation.
