Seismographic networks: Problems and outlook for the 1980s.

摘要

Seismographic networks collect the data fundamental to the science of seismology, providing recording of ground motion from natural earthquakes and other seismic sources ranging in size from the great earthquakes to the smallest detectable microearthquakes. This ground motion reveals. The seismographic networks are the basic scientific tools, that provide the continuing data base for the science. It is very important, to keep US-supported seismographic networks in the best operating condition, to provide networks with the latest technology, and to improve constantly the management and data bases of the networks. The importance of observational data from seismographic networks has not been recognized consistently by decision makers allocating funds among competing programs. The various governmental agencies responsible for network operations encounter many difficulties in obtaining adequate funding for the maintenance, upgrading, and the research associated with these important national facilities. This report is the result of a workshop convened at the request of several governmental agencies to review the status and associated problems of and the outlook for seismographic networks. Recommendations have been made to help solve the problems and to assure a viable observational capability for the future. 8 refs., 6 figs.
