SIMULATION OF NON-STATIONARY STRONG GROUND MOTIONS DURING PAST EARTHQUAKES BASED ON THE FAULT PARAMETERS AND THE SPECTRAL CHARACTERISTICS OF RECORDED ACCELEROGRAM
With an analysis of observed earthquake record, a simulation procedure is presented for estimating strong ground motions at any site during past earthquakes. The spectral characteristics of recorded accelerogram from past earthquake are examined and incorporated into the strong motion prediction model which is called EMPR-II, which can simulate the non-stationary time-history on the rock surface by superposition of the evolutionary power spectra with the given fault parameters, such as the fault length and the width, the seismic moment, the rupture pattern of the fault and propagation velocity of seismic waves. Some simulations of eathquake motion during 2007 Niigataken Chuetsu-oki earthquake are presented for the purpose of investigating the structure damage.
