Abstract: In order to compile the monthly report of crustal deformation monitoring data, based on the earthquake precursor data management system of Hebei Province and Zhangjiakou sub center, the software of monthly report of crustal deformation monitoring data at Huailai station is programmed in VB and VBA language, and word documents are quickly generated. According to the compilation requirements of the monthly tilt (strain) and volumetric strain reports of the crustal deformation discipline management group, the software realizes the correction of observation logs, and implements the automatic filling and submitting of texts, tables and graphs of instrument status, grid value usage, missing measurement statistics, preprocessing, seismic records, observation curves, etc. The writing of monthly reports is standardized, fast and accurate, which improves the work efficiency and has the value of application and promotion.
