National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

World-Wide Standardized Seismograph Network: A Data Users Guide.

Publication Date	2014

Abstract	Our primary source for the early history of the World-Wide Standardized Seismograph Network (WWSSN) is an article by Oliver and Murphy (1971). Their article includes the rationale for creation of the network, station siting, recording bands and instrumentation, and concludes with a review of preliminary results using network data. The following paragraphs include a summary of some topics discussed in their article.Seismologists had long recognized the need for a global network of accurately calibrated and accurately timed seismographs in the years before the World-Wide Standardized Seismographic Network was installed. The opportunity to fill that need came as a result of nuclear test ban discussions held in 1958. A panel on seismic improvement, chaired by Dr. Lloyd Berkner, was formed in the United States to consider research needs for improving the national capability in the detection and discrimination of underground nuclear explosions.2 The panel’s report formed the basis of Project Vela Uniform, a program of fundamental and applied research managed by the Defense Advanced Research Projects Agency (DARPA). One of the panel recommendations was for the installation of standardized seismographs, with accurate clocks, at 100 to 200 existing seismograph stations. The new network was not intended for the surveillance of nuclear tests; its role was to produce the data needed for fundamental research in seismology. The recommendation of the project was adopted and implemented as the World-Wide Standardized Seismograph Network. The WWSSN was a technological milestone in seismology, producing abundant high quality data for research. The precedent-setting program also created a global network infrastructure, including the data-exchange procedures and station technical capabilities needed to support the establishment of the more advanced networks in operation today.
