This repository provides Matlab scripts to model spatial correlation in earthquake ground motions, and quantify estimation uncertainty. Further documentation can be found in the following paper:
Baker, Jack. W., and Chen, Yilin. (2020). “Ground motion spatial correlation fitting methods and estimation uncertainty.” Earthquake Engineering & Structural Dynamics, 49(15), 1662–1681. https://web.stanford.edu/~bakerjw/Publications/Baker_Chen_(2020)_Spatial_fitting,_EESD.pdf
The script MAIN_script.m in the root directory will produce the data and figures used in the above manuscript.
The script MAIN_variogram.m in the "simple fitting example" folder will perform a very simple computation of a semivariogram and model fit, to illustrate the basic mechanics of geostatical calculations.
