Abstract
The Geophysical Service of the Russian Academy of Sciences (Obninsk, Moscow Region) made it possible to process seismograms of “Mirnyy” station in Antarctica. Seismograms for the period 1961–1991 were viewed, when underground nuclear explosions were conducted at the Nevada Test Site of the United States. To calculate and construct a local travel time curve and a linear trend of the PKIKPBC body wave travel time on the Nevada Test Site (NTS) – “Mirnyy” seismic station (MIR), 120 seismograms from Kirnos seismograph (SVKM) were selected for the period May 13, 1966 – October 18, 1991: 60 for each site Pahute and Yucca of the Nevada Test Site (NTS). The article presents local travel-time curves and linear trends of the PKIKPBC wave on the travelpath NTS – MIR. Increase in time travel with years as in travelpaths Nevada Test Site – Borovoye [14]. Dependency of arrival times of the PKIKPBC wave on mb magnitude was detected. The obtained data can be used for comparison of results of PKIKPBC wave study from the Nevada Test Site on other stations, for examples, at “Novolazarevskaya” Antarctic station.
