В статье рассматриваются времена пробега продольных волн для 8 взрывов Yucca Flat (Невадский Испытательный Полигон NTS) с 1979 по 1984 гг. с магнитудами mb = 4,9–5,9. Времена пробега получены при пересмотре сейсмограмм из архивов Института динамики геосфер им. М.А. Садовского для подсистемы «Ожерелье» периферийных пунктов Зеренда, Восточное, Чкалово большебазовой системы сейсмического группирования (БСГ) геофизической обсерватории (ГО) «Боровое». Данная система работала с 1979 г. на территории Казахстана. На примере регистрации подземных ядерных взрывов на площадке Yucca Невадского испытательного полигона (NTS) исследуются локальные годографы и линейные тренды времени пробега продольной волны в диапазоне эпицентральных расстояний 89,3110°–90,3701°. Сделаны оценки скоростей продольных волн для трасс Yucca-Ожерелье и периферийных пунктов.

This paper presents the travel times of P waves for 8 Yucca Flat (Nevada Test Site NTS) explosions from 1979 to 1984, with magnitudes mb = 4.9–5.9. Travel times were obtained by revising seismograms from the archives Sadovsky Institute of Geosphere Dynamics for the subsystem “Ozherel’e” (Necklace) of peripheral points Zerenda, Vostochniy, Chkalovo of the large-base seismic array system (SAS) of the geophysical observatory Borovoye. This system has been operating since 1979 on the territory of Kazakhstan. By the example of registration of underground nuclear explosions at the Yucca site of the Nevada Test Site (NTS), local travel time curves and linear trends in the P wave travel time in the range of epicentral distances 89.3110°–90.3701° are investigated. We estimate of the velocities of effective P waves for the Yucca-“Ozherel’e” and peripheral points.
