Abstract
A method may include acquiring raw seismic data, computing event location and corresponding P and S wave arrivals, automatically obtaining polarity of the corresponding P and S waves arrivals, measuring fit of P and S wave polarity to a model to obtain a group of accepted solutions, analyzing distribution of the accepted solutions in the model, and identifying a best solution as a focal mechanism.
