Seven indices, i.e., peak ground acceleration, peak ground velocity, spectral intensity, instrumental seismic intensity, power spectral intensity, predominant period, and maximum shear strain, are chosen as earthquake motion indices. Two vertical array records, the Kushiro port during the 1993 Kushiro-oki earthquake and Port Island during the 1995 Kobe earthquake, are analyzed by the equivalent linear, total stress truly nonlinear and effective stress analyses and compared. Effective stress analysis showed good agreement with observed records. Parametric study by means of scaled input earthquake motion indicates that difference of analytical methods are very small when maximum shear strain is less than 0.1 %, but it increases as the maximum shear strain increases. The radar chart was very convenient to evaluate the accuracy of the result of analysis because error can be seen from variety of stand point in one glance.
