CONTRASTIVE ANALYSIS TO THE DIGITAL AND ANALOGUE DATA OF CRUSTAL DEFORMATION IN ZHANGJIAKOU SEISMOSTATION

    Graphical Abstract
    • Abstract
  • the geological structure of Zhangjiakou Seismostation and its digital reconstruction in crustal deformation observation are introduced. The accuracy of the digital and analogue data observed in 2002 is contrasted. The cause of difference and the dependence of observation data with auxiliary observation data are analysed. The results show that the digital data is good in continuity and quality, can replace the analogue data.
