В годы холодной войны 20 века и засекречивания информации между крупнейшими ядерными государствами Советским Союзом (СССР) и Соединенными Штатами Америки (США) данные о регистрации ядерных взрывов не публиковались, однако подземные ядерные взрывы (ПЯВ) были записаны сейсмическими станциями.

Садовского (ИДГ РАН). Лишь после 1985 г. отчеты с некоторых сейсмических станций бывшего СССР стали публиковаться в оперативных сводках Объединенной геофизической службы Российской академии наук (ГС РАН). Так как она еще нигде не публиковалась, мы собираем их и получаем времена пробега путем ревизии сейсмограмм из архивов ИДГ РАН и ГС РАН для пяти Курило-Камчатских сейсмостанций (Беринг, Эссо, Северо-Курильск, Курильск и Петропавловск). 48 ПЯВ Соединенных Штатов в Пахьют Меса (на испытательном полигоне в Неваде) с 1968 по 1990 год используются для построения годографа продольных волн. Мы измеряем времена пробега P-волн (tp) на исторических сейсмограммах для трассы между испытаниями на Пахьют Меса и станциями Курило-Камчатского региона. Магнитуда объемных волн (mb) варьируется от 5.3 до 6.5. Получено: 1 ПЯВ на ст. Беринг, 7 ПЯВ на ст. Эссо, 45 ПЯВ на ст. Петропавловск, 18 ПЯВ на ст. Северо-Курильск и 12 ПЯВ на ст. Курильск. Мы строим функцию времени пробега, используя алгоритм линейной регрессии как tp=k·Δ°+b, где Δ° – эпицентральное расстояние, k и b – произвольные константы. Показано, что отклонения времени пробега связаны с нелинейностью Земли. Оценены эффективные скорости продольных волн для трассы Пахьют Меса – Курилы – Камчатка как коэффициент k в линейном уравнении. Эффективная скорость равна 7,5 км/с.</p></abstract><trans-abstract xml:lang="en"><p>This research fulfills additional information about the lithosphere below Southeastern Asia and the northern Pacific. The area is interesting for researchers because of the Kuril–Kamchatka subducted lithosphere. The availability to study an underground structure is complicated, because of Pacific Ocean. The significance of this research concerns epicentral distances ~54°–70° or ~6000–7000 km. During the Cold War of the 20th century and the classification of information between the largest nuclear states the Soviet Union (USSR) and the United States of America (USA), data on the registration of nuclear explosions were not published, however, underground nuclear explosions (UNE) were recorded. Thanks to an employee of the laboratory 5-s of the Institute of Physics of the Earth named after O.Yu. Schmidt of the USSR Academy of Sciences Kh.D. Rubinstein is kept at the Institute for the Dynamics of Geospheres of the Russian Academy of Sciences named after Academician M.A. Sadovsky (IDG RAS). Only after 1985 reports from some seismic stations of the former USSR began to be published in the operational reports of the United Geophysical Survey of the Russian Academy of Sciences (GS RAS). As it has not been yet published anywhere, we collect them and obtain the travel times were by revising seismograms from the archives IDG RAS and GS RAS for five Kuril–Kamchatka seismic stations (Bering, Esso, Severo-Kurilsk, Kurilsk). The 48 Unites States UNE at Pahute Mesa (at Nevada Test Site) from 1968 to 1990 are used for travel time curve building. We measure P waves travel times (tp) on historical seismograms for the ray travel path between Pahute Mesa tests and Kuril–Kamchatka stations. The body-waves magnitudes (mb) vary from 5.3 to 6.5. We obtain arrivals for: 1 UNE at Bering station, 7 UNE at Esso station, 45 UNE at Petropavlovsk, 18 UNE at Severo-Kurilsk and 12 at Kurilsk. We build a travel time function using linear regression algorithm as tp=k·Δ°+b, where Δ° is the epicentral distance, k and b are arbitrary constants. We show that travel time deviations, associated with nonlinearity of the Earth. We estimate the effective velocities of P waves for the Pahute Mesa – Kuril–Kamchatka travel path as coefficient k in the linear equation. Effective velocity is equal to 7.5 km/s.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>волна</kwd><kwd>скорость</kwd><kwd>время пробега</kwd><kwd>телесейсмическое расстояние</kwd><kwd>Невадский испытательный полигон</kwd><kwd>Курило-Камчатка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>P wave</kwd><kwd>velocity</kwd><kwd>travel-time</kwd><kwd>teleseismic distance</kwd><kwd>NTS</kwd><kwd>Kuril–Kamchatka</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>The work was carried out within the framework of the state assignment of the Research Station of the Russian Academy of Sciences in Bishkek 1021052806454-2-1.5.1</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ан В.
