We estimated the fault of the 1924 Tanzawa earthquake (<i>M</i>j7.3), which was the largest aftershock of the 1923 Kanto earthquake (<i>M</i>s8.2). We could successfully reproduce the observed waveforms in central of Tokyo based on the estimated fault model. This is very important to investigate the characteristics of ground motions by M7 events occurring in the Tokyo Metropolitan area because we only have a few observed waveforms of such events in central Tokyo. Finally, we calculated ground motions around Tokyo metropolitan area by the estimated fault model. The simulated ground motions do not exceed the design spectra around the area but in west of Kanagawa Pref.
