RefPick: A GUI Application to Pick First Arrival Times and Data Processing on Seismic Refraction Data

The quantified interpretation of the seismic refraction record depends on correct and confident picking first arrival times. However, traditional first arrival picking techniques are not enough if the refraction data are poor. This study presents the implementation of a GUI interface, RefPick, which has been established to detecting first arrivals on seismic refraction data, also data processing and inversion. While the interface allows picking the first arrival times by semi-automatically based correlation technique and manually, in addition, the seismic data can be filtered by f-k and Butterworth filters. The interface provides to export the first arrivals in the format of common evaluation software. Also, the inversion will be useful to invert the first data set within RefPick interface. By means of the RefPick, a seismic refraction data can be evaluated within one user-friend, open source GUI application.
