• Resumen

  • In 1980, the State Seismological Bureau (SSB) of the People’s Republic of China, the U.S. Geological Survey (USGS), and the U.S. National Science Foundation (NSF) signed the Earthquake Studies Protocol to initiate research programs for the benefit of the earthquake hazards reduction programs in both countries (Russ and Johnson, 1985). Because high‐quality seismic data are essential to earthquake studies, one of the first elements of this protocol was the establishment of the China Digital Seismograph Network (CDSN; Fig. 1 and Embedded Image Table S1, available in the electronic supplement to this article.).

    The CDSN was designed as a national facility, building on existing Chinese observatories where possible. Implemented by the SSB Institute of Geophysics (IG) and USGS Albuquerque Seismological Laboratory (ASL), the first phase of the network was installed in 1985–1986 and consisted of nine stations (BJI, Baijiatuan; ENH, Enshi; HIA, Hailar; KMI, Kunming; LZH, Lanzhou; MDJ, Mudanjiang; QIZ, Qiongzhong; SSE, Sheshan; and WMQ, Urumqi) with network code CD. Under the terms of the original CDSN agreement, the SSB provided the equipment for five data acquisition systems, and the USGS supplied four (Institute of Geophysics et al., 1987). The USGS systems were installed at Baijiatuan, Kunming, Lanzhou, and Mudanjiang; the SSB systems were installed …
