This paper presents a procedure of nonstationary spectrum analysis by using complex demodulation with which both accurate evolutionary spectrum and nonstationary phase variation can be directly estimated. Furthermore, the record of an actual strong seismic motion, that is, the N-S component of Muroran acceleration record (1968) is analysed to demonstrate the applicability of the present analytical method. The set of results indicates that the method of complex demodulation is an effective and reliable method of evaluating evolutionary power spectrum and phase of a strong earthquake motion.
