The JMA seismic intensity and other ground motion indices (e. g., PGA, PGV and SI) were calculated using 17 liquefied records selected from 7 major earthquake events. The relationships between the JMA seismic intensity and PGA, PGV and SI were then derived performing a linear regression analysis. Results from the analysis show that the JMA seismic intensity shows higher correlation with SI than PGA or PGV, and it shows the highest correlation with the parameter such as the combination of PGA and SI. The obtained relationships are also compared with the ones obtained from non-liquefied records, and it will useful for the disaster management agencies in Japan and deployment of new SI-sensors, which monitor both PGA and SI.
