摘要

The number and density of strong-motion observation stations in mainland China was seriously behind the number in the United States, Japan, Iran, and Mexico prior to the year 2000 (Xie et al. 1982; Gao et al. 2001; Zhou 2006; Nozu 2004). The existing accelerograph network could not meet the needs of research, engineering, and construction in China. To improve the situation, the nation provided funds to implement construction of the National Strong Motion Observation Network System (NSMONS) of China in the 10th National Five-year Plan. The project considered the existing strong-motion stations, seismicity in all regions and cities, and the distribution of major engineering structures. It also considered the research and construction needs and trends to build the NSMONS. The network focuses on regional distribution of permanent stations, stations in major cities for rapid reporting of intensity, and special arrays for special research purposes, as shown in Figure 1. The network is augmented with mobile observations and includes the National Network Center and Regional Network Centers for record recovery, processing, and dissemination; and network technical support, management, and maintenance.
