The air-gun source, first invented in the 1960s, is mainly used in the field of oil exploration. It has high precision, good repeatability, and is non-polluting; thus, it has gradually become an important artificial source in geophysical detection area. The earthquake administration of Fujian Province efficiently completed the construction of its air-gun source system and has successfully carried out a series of air-gun explosion experiments in 2014 and 2015, thus providing valuable observation data for further research. Considering that the experimental conditions of the air-gun array and the explosion conditions directly affect the explosion performance, researchers have designed a series of air-gun explosion experiments under different experimental conditions. After each experiment, the explosion capability must be quickly analyzed to determine an optimal operating condition for the consecutive explosion issue. At present, the whole analysis work is completed by manual work. This process requires a lot of work, time, and effort, so analysts need to work overtime. Thus, this process is not only inefficient but also subjective because different analysts may provide different results. Considering the further application of this repeatable source, a new method based on the correlation coefficient method is proposed to automatically analyze and display the distribution of air-gun trigged stations. Analysis results show that the new method obtains the same results as the artificial judgments. The K24 and K36 experiment results show better explosion effect. Moreover, over 70 stations received the signals of single firing, with signals that can be recorded by stations beyond 200 km. After repeating the firing for 50 times, over 90 stations received the signals, which can be recorded by stations beyond 226 km. The automatic detection method provides a faster and more objective way to demonstrate the distribution of the trigged stations, thus significantly contributing to the air-gun explosive effect evaluation process. The automatic detection method was successfully applied in subsequent experiments carried out in the Mianhuatan Reservoir (Longyan, Fujian) and Shihuangfeng (Wuping, Fujian).
