Quantifying Uncertainty and Kinematics of Earthquakes (QUAKES-A) provides an analytic center framework for creating a uniform crustal deformation reference model for the active plate margin of California by fusing InSAR, topographic, and GNSS geodetic imaging data. The objective is to provide tools for sampling spatial processes ranging from local to earthquake faults to broad tectonic deformation and temporal processes ranging from immediately following earthquakes to long-term tectonics. A reference model allows exploration of a uniform model and comparison to new data.
