G41A:
Geodetic Imaging and Interpretation of the Seismic Cycle I

Submit an Abstract to this Session



Session ID#: 30614

Session Description:
Geodesy’s ability to image earth processes has vastly improved both spatially and temporally in recent decades, making it an essential tool to study the seismic cycle and the ways the earth accommodates tectonic strain. To use geodesy to image these processes in a complex earth, it is essential to 1) correctly separate the contributions made by seismic, aseismic and nontectonic deformation in the data, and then 2) link these observations to fault and bulk processes with a full view of their spatiotemporal complexities. We welcome studies on all aspects of geodetic imaging of the seismic cycle: from improved techniques to detect tectonic signals (e.g. probabilistic, sparsity-promoting, etc.) and separate them from other deformation sources (e.g. hydrological, thermoelastic, anthropogenic), to the modeling and interpretation of the deformation mechanisms that produce them (e.g. coseismic slip, afterslip, viscoelastic relaxation, poroelastic rebound, slow slip events, long-term creep, gravity-driven postseismic deformation).
