Multiscale Interactions Between Foreshocks, Main Shocks, and Aftershocks: Observations and Physical Mechanisms Posters
Submit an Abstract to this Session
Session ID#: 45580
Session Description:
This session seeks contributions that advance our understanding of the physical mechanisms responsible for the multi-scale interactions between foreshocks, mainshocks, and aftershocks. While static stress changes are often considered the primary driving mechanism, other factors such as dynamic stress changes, fluid migration, poroelastic deformation, and aseismic slip can also promote earthquake triggering over various spatial and temporal scales. Moreover, the spatiotemporal evolution of such earthquake interactions may provide valuable information on the fault geometry and structure at depth, faulting styles, and the mainshock rupture process. We encourage seismic, geodetic, and geological observations that illuminate the fault structure and stress state associated with these interactions. We also welcome experimental, theoretical, and numerical results that provide physical constraints on the mechanisms responsible for the interactions.
