T21A:
Creep on Faults: Aseismic Slip Throughout the Earthquake Cycle Posters

Submit an Abstract to this Session



Session ID#: 24898

Session Description:
Aseismic slip is a significant mode of moment release on many faults, making spatiotemporal variations in creep an important area of research for understanding fault slip. The many flavors of fault creep include, but are not limited to: interseismic creep, afterslip, and triggered or spontaneous slow slip. Observational, experimental, and modeling studies of creeping fault behavior have recently shed light on the richness of aseismic slip processes in nature, and have revealed that faults display many combinations of seismic and aseismic moment release at different phases of the earthquake cycle. However, much remains to be understood about the frictional and other physical properties responsible for this behavior, and to what extent they are stable over time. In this session, we invite all contributions to the study of fault creep from the interseismic to postseismic phases of the earthquake cycle, including observational, laboratory and modeling investigations.
