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 aspects of a key component of the geodetic slip rates models - aseismic slip on creeping faults. The fault creep not only removes fault slip from the budget of total slip dictated by tectonic plate motions, but it affects the overall interpretation of the geodetic data in terms of fault locking effects that matter for seismic hazard. The effects of fault creep must be corrected for in order for geophysical models of long-term fault slip rates to be constructed. Estimating these effects is challenging and requires considerable effort to assemble relevant data that permit identification of creeping and the discrimination of aseismic slip from fault locking. The Contractor's efforts will include gathering the relevant data and preparing them for geophysical inversions by other members of the Tectonic Geodesy Disciplinary Group. This acquisition will be processed in accordance with the procedures of FAR Part 12, entitled, ¿Acquisition of Commercial Items¿ and FAR Part 13, entitled, ¿Simplified Acquisition Procedures¿. Solicitation 140G0321Q0001 will be made available through the Government-wide Point of Entry (GPE) on or about 13 November 2020, IAW FAR 5.102(a)(1). All responses must be in writing by email to the Student Trainee (Contracting) at yangzhideng@usgs.gov.
