- Principal directions and components are generated for the strong ground motions recorded during the San Fernando earthquake of February 9, 1971. Characteristics of the principal components are investigated using the moving-window technique applied in both the time and frequency domains. A nonstationary random process is defined reflecting these same characteristics in a statistical sense. A computer program for generating principal directions and components of motion, wave-form characteristics, and sample accelerograms from the nonstationary random process is listed.
