The Soil response effects for two sites in San Salvador (IGN and UCA) were evaluated using one-dimensional wave propagation models. The strong motion records of the October 10, 1986 earthquake were used to verify the numerical simulations. The recording at the Sheraton Hotel, after the process of deconvolution, was used as the reference bedrock outcrop input motion in all simulations. Result of the analyses showed that the non-linear, time domain model (AMPLE) gave somewhat better results compared to the quasi-linear, frequency domain model (SHAKE). However, the were some discrepancies between the AMPLE simulations and the recorded motions at frequencies lower than 1.4 Hz. This was probably caused by the presence of low frequency surface waves, which were not modelled in the simulations (Au) - en
