Abstract: As the basic unit of seismic system, seismic station is the basic organization to set up earthquake monitoring facilities and carry out earthquake monitoring. Complete earthquake monitoring facilities and good earthquake observation environment are the basis of earthquake observation. Mastering the complete and accurate basic information is good for management. For the update of observation equipment, the change of observation environment and the difference of construction conditions, the basic information of seismic stations is different from the initial state. It has an impact on the accuracy and effectiveness of seismic data. This paper discusses the significance of improving the basic information of seismic stations, the application of basic information in observation interference investigation, observation environment protection, and upgrading of seismic stations. It aims to draw the industry’s attention to the collection, management, and application of basic information of seismic stations, so as to ensure the scientific and effective seismic observation data.
