中国国家地震局和美国地质调查局于1983年5月14日在北京签署了关于合作建设中国数字地震台网的原则协议。根据协议,该台网将由北京,兰州、恩施、昆明、琼中、上海、乌鲁木齐、海拉尔、牡丹江等九个数字化地震台站和设在北京的台网维修中心及数据管理中心组成。几年来,在中美双方的通力合作下,该数字化地震台网已于1986年7月成功地完成了全部设备的安装、调试工作,并继而转入试运行阶段。经过一年多时间的地震观测和数据处理,中美双方于1987年10月21日至23日在北京召开了台网测试验收会议并举行了庆祝台网建成剪彩仪式。 China Earthquake Administration and the United States Geological Survey on May 14, 1983 in Beijing signed a cooperation agreement on the construction of China’s digital seismic network agreement. According to the agreement, the Taiwan network will consist of nine digital seismic stations in Beijing, Lanzhou, Enshi, Kunming, Qiongzhong, Shanghai, Urumqi, Hailar and Mudanjiang, as well as a network maintenance center and a data management center in Beijing. Over the past few years, with the concerted efforts of both China and the United States, the digital seismic network successfully completed the installation and commissioning of all the equipment in July 1986 and was subsequently put into trial operation. After more than a year of seismic observation and data processing, both China and the United States held a Taiwan network testing and acceptance conference in Beijing from October 21 to October 23, 1987 and held a ceremony marking the completion of the ribbon-cutting ceremony.
