Use of the stochastic-source model to simulate ground motion and response spectra in northern Vietnam

► Stochastic method for generating artificial ground motion. ► Determination of response spectra due to moderate magnitude earthquakes. ► Provides a brief generation of artificial ground motion procedures. ► The simulated waveforms were employed to two levels (VN L1 and VN L2) predicted ground motions in Vietnam. ► The new target response acceleration spectrum is proposed within the short period.
