Discussion on common problems in data tracking and analysis of geomagnetics

The tracking and analysis of precursor network observation data is comprehensively carried out at precursor stations and regional centers. The event records generated by the tracking and analysis of earthquake precursor data demonstrate the dynamic changes of precursor network observation data. This article starts from the current situation of data tracking and analysis, proposes precautions for data tracking and analysis in the field of geomagnetism, and discusses common problems in geomagnetic tracking and analysis through multiple aspects such as event leakage analysis and over analysis, data type selection, event start and end time, event analysis description, map drawing and annotation, event type classification, geophysical event analysis, and proposes corresponding solutions, measures are proposed for the promotion of data tracking and analysis in the field of geomagnetism. We hope to provide reference for the observation personnel of geomagnetic stations to better carry out data analysis research and output application work, provide a solid foundation for the prediction and scientific research of geomagnetic disciplines, and promote the shift of the focus of daily work of earthquake precursor networks from observation to both observation and application.
