T42B:
Bridging Earthquakes and Earth Structure: Reconciling Deformation Observed over Geologic and Geodetic Timescales I


Submit an Abstract to this Session


Session ID#: 57140

Session Description:
Deformation constrained by geodetic and geologic observations may or may not agree with one another, because these measures archive the response of Earth’s crust to loading over vastly different timescales.  For example, geodetic measures of deformation may record elastic bending, viscoelastic flow of the crust and mantle, and interseismic fault-zone creep, while geologic observations may additionally represent the effects of plastic yielding and changes in structural geometries that attend sustained loading over these longer time-scales.

We solicit submissions that address, quantify, and compare deformations measured over timescales ranging from seconds to millions of years. We welcome contributions that combine numerical models with geologic, thermochronologic, geomorphic, paleoseismologic, and geodetic measures of deformation and/or exhumation, which together may provide insight into the processes responsible for deformation over these different time-scales.
