Prediction of Aftershocks Distribution Using Self-Organizing Feature Maps (SOFM) and Its Application on the Birjand-Ghaen and Izmit Earthquakes

In this paper, an advanced formulation of time-domain two-dimensional Boundary Element Method (BEM) for linear elastodynamics is used to carry out site response analysis of topographic structures subjected to incident P-, SV-, and Rayleigh waves. A modified set of well behaved full space two-dimensional elastodynamic convoluted kernels is presented and employed, that has a higher degree of accuracy than those presented by the previous researchers. Numerical results are presented, including cases of half-plane, canyon and ridge sections, subjected to the different body and surface waves.
