A method of correcting a representative displacement waveform includes a step of determining a performance curve that is configured, based on frequency analysis of measured acceleration waveform of a seismic wave, to reflect a determined frequency band of the measured acceleration waveform and not to reflect a frequency band other than the determined frequency band; a step of determining an approximation formula approximating the performance curve; a step of determining a virtual displacement waveform by applying the measured acceleration waveform of the seismic wave to the approximation formula; a step of determining, through frequency analysis of the virtual displacement waveform, a displacement waveform for correction which reflects at least partially the frequency band other than the determined frequency band; and a step of correcting, in accordance with the displacement waveform for correction, a representative displacement waveform used as a basis for the performance curve. |
