OPERATION OF A LONG PERIOD SEISMOGRAPH NETWORK UTILIZING MAGNETIC TAPE RECORDING AND ANALYSIS OF DATA RECORDED ON MAGNETIC TAPE
Abstract
The worldwide network of long-period seismographs recording on magnetic tape established under the sponsorship of AF19(604)-8485 has been operated continuously under the present contract. The stations at Mt. Tsukuba, Japan; Honolulu, Hawaii; Uppsala, Sweden; Huancayo, Peru; College, Alaska; Canberra, Australia; and Palisades, New York, have produced large amounts of valuable data. Many studies utilizing this data have been carried out and several of these are of particular significance to the VELA-UNIFORM program. These include: the relative excitation of surface and body waves by the underground nuclear explosion Long Shot, the magnitude and AR measurements from nuclear explosions and earthquakes in the Western United States, the determination of energy radiation patterns for GNOME, HARDHAT, and the New Madrid and Hebgen Lake earthquakes, the amplitude frequency content and travel times of PcP from nuclear explosions and earthquakes. These studies together with many others utilized the data from this network and indicate the value of this type of recording.
