This paper exemplifies and validates a recently developed model-data fusion algorithm in spatial and statistical characterization of the elastic soil parameters at any geotechnical sites from geophysical measurements. Advanced geophysical test measurements available for the NEES@UCSB site in Garner Valley, CA, are analyzed to probabilistically estimate the Young's modulus and Poisson's ratio of soil at a 60 m×60 m parcel of the site up to a depth 40 m. The probabilistic estimates of the soil parameters are presented in terms of the mean and standard deviation profiles as well as correlation structures in the x-, y-, and z-direction.
