Earthquakes are dynamic events, but leave permanent markers of rock deformation and displacement. Geologic field studies identify these permanent markers, often used to determine the magnitude of slip in past earthquakes and combined with dating techniques to determine long-term rates over multiple earthquake cycles. Geophysical methods track ongoing plate motions and earthquake-cycle deformation captured by satellites using techniques involving GPS and InSAR. Analog and numerical models capture long-term geologic deformation and/or short-term dynamic behavior associated with earthquakes. However, in order to best advance both seismic hazard mitigation and earthquake science, the methods and results from these different lines of inquiry should be integrated and well understood by all. This is critical as we face the challenge of accounting for complex fault geometry and ruptures, off-fault damage and distributed deformation, all of which have been revealed as common features in recent earthquakes. Modeling can fill gaps in observational data, target future field sites and help determine the processes responsible for observed deformation features. Likewise, observational data is critical to characterizing earthquake behavior and provides necessary constraints on modeling input and output. This session aims to bring together scientists from these different lines of study to facilitate mutual understanding and collaboration. We encourage submissions that are methods- and/or results-based studies across structural geology, paleoseismology, Quaternary geology, geodesy and modeling of fault behavior and earthquake dynamics.
