<br/><br/> The response spectra of earthquake records from Tohoku District of Japan are analyzed in terms of the displacement, velocity and acceleration  response spectra. Observations of spectral behavior considering individual. stations recording different earthquakes, groups of stations having different site characteristics and stations with the same base rock movement are explained with reference to local soil conditions. Various  parameters which influence the response spectra are minimized by normalization or by proper choice of earthquake records. It is found that the response spectra of earthquake motions are related to the depth and  nature of soil deposits underlying the recording stations.
