Analysis and research on the quality of observation data of Zhaotong Xunlong seismic station

Based on the quality evaluation results of the national seismic stations from 2018 to 2021 at Zhaotong Xunlong seismic sation, the improvement data analysis is given by analyzing the deduction of points and the reasons for the problems over the years. Combined with the actual situation of the station, corresponding experience and technical countermeasures such as level and strengthening system operation ability are presented. In order to improve the quality of seismic observations at the Zhaotong Xunlong seismic station in the future, it provides a principle to follow and significance guide for the improvement of the quality of the seismic observation data for this station and its brother stations.
