Crustal deformation of the Earth encompasses both short-term deformation over decadal timescales as well as long-term deformation over geological timescales. Short-term deformation is well-imaged by geodetic and seismological methods, but untangling short- and long-term processes from decadal-scale observations can be difficult. We therefore rely on geological, thermochronological, and geomorphological tools to provide insight into processes that build tectonic structures. Important feedback mechanisms exist between short-term and long-term processes, but it remains difficult to reconcile the tools and scales employed to study short-term versus long-term processes. Since observations of coupled processes across these disparate temporal scales are challenging, we rely on numerical modelling techniques to shed light on the interplay between long-term and short-term processes. This session encourages submissions from geology, tectonics, geophysical modelling and observations, and geodynamic modelling to discuss the complexities involved in combining these processes and novel methods to reconcile geological and geophysical data in a unified model
