| Abstract: | Seismic signal detection is the main task of different seismic data analysis and process. Because STA/LTA method has the features of simple algorithm and real-time processing, so it＇s widely used in the seismic signal detection. The application of this method to signal detection of local earthquake events has different effects of seismic trigger, which is influenced by different parameters. In this article, the influencing factors of seismic signal detection u sing STA/LTA method with actual earthquake events are studied, and the most reasonable parameters of seismic signal detection are given. The results provide a reference for parameter setting of seismic signal detection in regional seismic network. |
