Abstract:

During 1976-1987 in the territory of Eastern Siberia (the Siberian platform, Chitinskaya area and Yakutia) ten peaceful nuclear explosions (PNEs) were conducted. The PNEs' magnitudes ranged from 4.8 to 5.3. Explosions were measured by regional analogue seismic station networks located in the Baikal rift system (FDSN code is BY) at epicenter distances from 246 to 1407 km. Regional travel times distributions for the regional seismic phases (Pn, Pg, Sn, Sg and Rg) were constructed using arrival times of 9 PNEs. Reconstruction of PNE epicenters was carried out using the HYPOICENTER software. In the future, these data may be used for understanding the deep structure of the region.
