Calculation of eigenquakes from an earthquake record suite, and reproduction of the initial earthquake suite from the basis eigenquakes. It is found that the difference between the initial records and their corresponding simulated ones is small. Eigenquakes can be used for the generation of artificial earthquake ground motion records for the dynamic analysis of structures during their seismic design.
