The quality review of the seismic breakdown records depends on the accurate and reliable determination of the first arrival times. The obtaining of first arrival times through a graph or image makes the labels related to external factors such as the scale and quality of the data display, the width rate, the sensitivity of the labels, the user's experience that makes the labels. When the first arrival sign of the data containing noise, the situation becomes more complex. The cross-relation process commonly used in the processing of reflective data in this study has been used to mark the first arrival times in noise or noise-free seismic breakdown data. Thanks to the prepared algorithm, the labels are made semi-automatic, the dependence of the first arrival times on the user is reduced, the erroneous labels that may be caused by environmental noise or display features are reduced, and the labels are based on a mathematical basis. The method developed was tested on 3 different noise content convergence models and field data with different noise characters obtained from different fields. The performance of the signs made is assessed by Ki-Kare error criterion. Furthermore, the differences between the small time differences between the arrival times marked by manual (handly, normal marking) and the arrival times marked by the help of the relation technique will create in the assessment of seismic breakdown data have been revealed by the breakdown tomography solutions.
