Spatial correlation of earthquake ground motion intensities

Example code to generate spatially correlated simulations of ground motion intensities at multiple periods, using Principle Component Analysis, as described in Markhvida et al. (2018).

Example code to generate spatially correlated simulations of ground motion intensities for a region. This code utilizes the OpenSHA event set simulator to generate earthquake ruptures and ground motion predictions, and supplements that code with features to generate spatially gridded locations and to simulate spatially correlated residuals.

Example code to illustrate the ground motion map selection calculations from "Ground-motion intensity and damage map selection for probabilistic infrastructure network risk assessment using optimization."
