A plan for the distribution of strong-motion instrumentation throughout the United States is outlined. The present national network of strong-motion instrumentation has evolved through the merger of several programs initiated by different agencies and organizations with objectives ranging from research to regulation. It is the result of the coordination of instrument maintainance and record keeping provided by the Seismic Engineering Branch of the U.S. Geological Survey. Concepts and strategies for planning and directing the development of the program include specific ground-motion and structural response studies. Certain regions in the United States are evaluated, in terms of activities and possibilities, in greater detail than in preliminary studies and make up the bulk of the report. They include the Northern, Central, and Southern California Coasts, Eastern California and Nevada, the Pacific Northwest, the Northern Rockies, Utah and Southeast Idaho, Colorado, New Mexico, Oklahoma, the Mississippi Valley, Ohio, the East Coast, Puerto Rico, Hawaii, and Alaska. The final section presents priorities and implications involved in the implementation of the program.
