COMPARATIVE ANALYSIS ON THE ABILITY OF DIGITAL AND ANALOG SEISMIC OBSERVATIONAL SYSTEM IN EARTHQUAKE DETECTION

    Graphical Abstract
    • Abstract
  • the region studied in the paper is west and middle areas of Inner Mongolia. The comparison of digital and analog observational systems shows that digital system has obvious advantage in the determination of initial phase, there are some deviations in origin time and epicenter position with analog system, but not large, so digital catalogue can basically be connected with analog catalogue.
