- Аннотация: The change in seismicity of the Garm region in Tajikistan after an irradiation of its crust with high energy electromagnetic pulses (EP) and after the Semipalatinsk nuclear explosions (NE) is considered. It's shown that the influence of EP, as well as NE, causes a statistically significant increase in the seismic activity and speed up the seismic energy release. Two areas of anomalous increase in seismic energy after irradiation and explosions adjoined to active faults were identified within the region. Both have a complex configuration in the form of two "petals" located in different sides of those faults. In both cases, one of the "petals" appears after EP, and the second after NE. It is shown that each of these "butterflies" constitutes as a whole anomalous area in which there are high tectonic stresses. The impact of NE has also been studied before beginning and after completion of these experiments. In both cases, those anomalous areas were not observed. Moreover after those experiments were completed, on distances of 50-70 km from the EP source no high stresses areas were observed at all. Consequently, the irradiation of the crust caused their relaxation on the area of about 3500 km2. However judging by the appreciable rise in seismicity caused by NE on the southwestern and southeastern margins, stresses had been increasing on periphery of the irradiated area.
