Strong motion records are often used as the ground motion inputs in the earthquake analysis and design of structures. In particular, for the design of underground structures, not only the time history at any particular point on the Earth's surface but also the space-time variation of the ground motion is needed. A method is developed for generating an artificial and simulated space-time variation which is characterized by a given cross-correlation function and includes a recorded strong ground motion at a point. Some examples of the application of the proposed method are given, and it is shown that a good convergence is obtained.
