The purpose of this research is to direct attention to the protection of the Einali historical monument located in the Sorkhab mountain range of Tabriz in terms of finding faults with the potential of destructive earthquakes based on the variogram analysis and spatial correlation pattern zoning of data related to recent earthquakes. Therefore, it is possible to protect the structure of the mentioned building by finding protection and strengthening solutions according to the outputs of the article. For this purpose, first, the faults around the Einali historical monument located in the central sector of the North Tabriz Fault (NTF) are identified based on the variograms related to the spatial data of the recent earthquakes. Direct identification of transverse faults in field studies is influenced by the geological environment of the region. For the study case, this environment includes structural complications such as many fractures and joints around the Einali building and the density of residential structures on the slopes of Sorkhab mountain. Therefore, providing an estimator tool in this study in order to identify and locate the fault segment can be helpful and beneficial because it is possible to choose the correct areas for field studies by having estimated positions with less time and cost. Locations according to the methodology presented in this study include the processing of the spatial position of recent earthquake data based on variograms, which results in the estimation of data with high spatial correlation. Therefore, by proposing a spatial pattern of continuous characteristics from variogram models and checking Kriging interpolation and choosing the best experimental variogram, the spatial correlation between observations was predicted for other unknown values. The results of the study showed a very high correlation of the separation revealed with the field evidence and, as a result, the validation of the method presented in this research. Therefore, it is suggested that the maximum amount of seismic damage to the Einali building is caused by the activity of the transverse fault associated with the NTF.
