IGCP 565 Workshop 3: Separating Hydrological and Tectonic Signals in Geodetic Observations Reno, Nevada, October 11-13, 2010

B1: Forward modeling of tectonic and hydrological signals

Co-Chairs: William Hammond (UNR), Jean-Paul Boy (University of Strasbourg)

This breakout session will discuss the current state of models for the prediction of geodetic signals resulting from tectonic and hydrological processes. We will evaluate the state of knowledge of the physics behind the Earth surface deformations and gravity changes on local to global spatial scales and various time scales. Examples of tectonic models include those describing earthquake deformation, postseismic transients, interseismic fault slip, creep, plate motions, etc.. Hydrologic models can include solid earth response to the motion of fluids, atmosphere, cryosphere, pumping, etc. We will evaluate the uncertainty in the sources and identify science challenges in improving the models and reducing the uncertainties. The session will be roughly 50% presentations and 50% facilitated discussion intended to gather input on the status and roles of models in interpreting geodetic observations.
