B--Geophysical modeling services to support the Tectonic Geodesy Disciplinary Grou

The U.S. Geological Survey Earthquake Science Center requires the geophysical modeling services to support the Tectonic Geodesy Disciplinary Group in collecting and providing datasets of crustal deformation rates around recognized creep faults. Geodetically-based fault slip rates rely on data from Global Positioning System networks which measure the crustal velocity field from tectonic deformation. Under the auspices of the Tectonic Geodesy Disciplinary Group these data are currently being assembled and will be interpreted by a team of geophysicists using physical models of crustal deformation. While a variety of models will be used (e.g. block models) all require the use of GPS data that is not contaminated by aseismic slip (also known as fault creep). The Contractor will focus on several
