Long period Fourier amplitude spectra of strong motion acceleration
AbstractThe empirical equations for scaling Fourier amplitude spectra in the frequency band from ~0·1 to 25 Hz can be extrapolated to describe the long period strong motion amplitudes. The results of this extrapolation can agree with (1) the seismological and field estimates of permanent ground displacement (near field), and with (2) the independent estimates of seismic moment and the observed frequencies of far field Fourier spectrum amplitudes.
