内容記述
I conducted some strong ground simulation based on source fault model during the 2008 Iwate-Miyagi inland earthquake. In order to estimate peak ground velocities at non-observation sites accurately, I approached to improve the calculation wave by using the frequency characteristics of the calculation and observed waves as well as the geographical information. I confirmed that the frequency characteristics of the calculation wave could be modified by the proposed method. Furthermore, it is strongly expected to obtain good accuracy ground motions (waveform and frequency characteristic) even at non-observation sites, if we could evaluated the phase properties of the waves adequately.
