Research Abstract |
Seismic source models are essentially important to reveal the characteristics of earthquakes. The waveform inversion becomes a popular tool to construct seismic source models. In the present study, we introduced uncertainty of Green's function into waveform inversion analyses. Applying the developed inverse method to real data set, we obtained a reasonable slip distribution and moment rate function without the non-negative slip constraint.
