Abstract
This letter proposes algorithms for the automatic identification of direct (Pg) and head (Pn) wave groups from first break readings of a deep seismic refraction profile. The process employs a split-and-merge fuzzy iterative prototype clustering technique to extract line segments from first arrivals. A constant velocity value is used as a threshold to identify Pg and Pn groups. Synthetic and real data were used to evaluate the algorithm with satisfactory identification results.
