From Earthquakes to Plate Boundaries: Insights Into Fault Behavior Spanning Seconds to Millennia
The processes of strain accumulation and release and related topographic evolution happen over disparate timescales – from seconds to millennia and longer. Quantifying and understanding the earthquake cycle in the continental crust and how tectonic strain is expressed at the surface in the landscape thus requires integrating methods that measure deformation at a range of timescales. While geodetic methods record regional infinitesimal strain accumulation over decadal timescales and finite coseismic deformation from individual large events, paleoseismology and tectonic geomorphology measure site-specific or regional-scale strain release over thousands to millions of years. Numerical modeling and analog experiments attempt to replicate processes that can span multiple temporal scales, but they must be validated with observations to ensure they are physically meaningful. In this session, we invite abstracts that integrate observations and methods from different temporal and/or spatial scales to address topics such as: surface rupture and slip distribution patterns in space and time; variations in earthquake timing and recurrence; fault growth, linkage, and scaling; (dis)agreement of geologic and geodetic rates; and tectonic landscape evolution. We welcome contributions from geodesy, earthquake geology, tectonic geomorphology, numerical modeling, analog experiments, and especially contributions with novel approaches to integrating multiple data sources that help further our understanding of strain accumulation and release spanning coseismic to geologic timescales.
