The description of the seismic source follows an approach proposed by Boore (1983). Boore’s method starts with the generation of a gaussian white noise. A window is applied to the noise which has the form

a is set to 1 since the scaling is done in the frequency domain, H(t) is the Heaviside function, and [...]

Seismic source spectra in terms of displacement density[4] can be described in terms of a low pass filter, i. e., with a flat part at low frequencies, an intermediate part where the spectrum starts to decrease, and the high frequency part where we note a steep decay, often proportional f-g, where the spectral roll off [...]
