Temporally Variable Records of Earthquake Behavior and Considerations for Seismic Hazard Analyse
Geologic data used to constrain past earthquakes – geologic slip rates and paleoseismic chronologies – are inherently time-variable data streams due to irregular earthquake occurrence through time. While time-varying by their nature, these records are used to extrapolate and infer long-term fault behavior, most notably in time-independent seismic hazard analyses. We seek submissions discussing new contributions in the field of earthquake geology, particularly studies geared to address time-dependence of geologic slip rates, paleoseismic chronologies and recurrence intervals, regional geologic deformation models, and displacement and/or surface rupture variability at a point through time. We also welcome contributions comparing geologic data to geodetic deformation models to further assess discrepancies rooted in sampling decadal (geodetic) vs. longer (geologic) time scales. We encourage submissions that pose ideas for the implementation of these geologic data in future time-independent and time-dependent seismic hazard model development.
