Abstract

This article is intended to predict a seismogram at sites other than those from which the model is calibrated using the two well-known stochastic point-source and finite-fault approaches. The two models are implemented on the 2005 Zarand earthquake as a case study. For this purpose, the models are validated against recordings at four stations through demonstrating a good agreement between the elastic response spectra corresponding to the synthesized and recorded data, confirming the reliability of the two models. Additionally, a quality factor and maximum cut-off frequency are proposed for the Zarand region (Iran). It is concluded that the models can be used to predict seismogram for engineering purposes in the Zarand region.
