Fuzzy logic approach on earthquake locations

Location of regional earthquakes usualy has erors because of the poor quality of recorded phases and/or very large gap in seismograph geometry. In this study, we attempt to locate seismic events using P-P, S-S and S-P travel time intervals with fuzzy logic approach. We first tested method on theorical data and developed new approach. Based on experienced that we got from test results, we apply the method on the earthquake data, relocate the earthquakes and then compare the results with location of this earthquakes that determined by zSacWin location program.
