The criteria of Somerville et al. (1999) was applied to the slip distribution rupture model (Sladen et al, 2010) obtaining a two asperities source model as initial approach of the SMGAs. The observed waveforms of the mainshock were also divided in two wave packets to compute the contribution from each SMGA independently, by using two aftershocks (Mw5.6 and Mw5.0) as Empirical Green’s functions (EGF). The spectral analysis of the waveforms did not follow the omega-squared source spectra model, therefore the SMGAs (SMGA1 and SMGA2) were obtained by a grid searching, considering correlation coefficients and visual comparisons between the successive observed and synthetic waveforms. The agreement between the observed and synthesized waveforms from SMGA2 were poor, compared with those for SMGA1, moreover the source area parameters and amount of average slips for asperities followed the scaling laws for interplate earthquakes.
