oa Automated Determination of Polarity and Amplitude Ratios for Estimation of Fault Plane Solutions

More than 5000 were localized with 924 recorded at more than 7 stations. Their polarities and amplitudes as well as beach balls were determined and plotted. 188 were recorded at more than 7 station and had a misfit of less than 10 are used for further studies and interpretations.

The automatization was a successfully applied to a data set of local seismicity in Northern Chile. Now it is less time consuming to pick polarities and amplitudes. The four criteria which were used to determine the parameters have to be defined more precisely in the future in order to increase the accurateness of the produced mechanisms. Another advantage lies in the application to not just seismology data sets but also microseismic data sets.
