The threat posed by earthquakes in the United States is actually a mosaic of different problems requiring different approaches to assessment and mitigation. Ours is the only country in the world that must deal with the diverse seismic hazards arising from the full range of earthquake environments, i.e., plate subduction zones (in the Aleutians and the Pacific Northwest)

The combined facilities of the national and regional networks, as proposed in this report, would constitute a National Seismic System, a satellite-based network capable of systematically monitoring and analyzing earthquakes throughout the nation within minutes of their occurrence. Such a system would maintain the vital regional research and response flexibility required by our nation's diverse seismic zones, and its dual components each would have significantly increased capabilities beyond those possible in isolation.

It should be fully implemented without delay. With it seismology can take a major step forward in the fundamental study of planet earth and in the determination of the earthquake hazard to which Americans are sublect.
