Abstractfulltext

We simulated the strong motion record obtained at the Esso Refinery station from the 1972 Managua, Nicaragua earthquake using its aftershock record through the empirical Green’s function method. In order to obtain the best initial guess for the modeling, we carried out the hypocenter relocation through the modified joint hypocenter determination method using the phase data listed in the ISC seismic catalog. Finally, we found out that the source model which best fitted to the observed waveform had two asperities. This asperity model fell on the trend of the empirical relation between the seismic moment and the strong motion generation area.
