This article presents the results of geological, structural, and hydrogeological investigations carried out before and after a large-scale explosion of an object located within the Semipalatinsk Test Site. The obtained data are compared with published information on aftershock emissions registered in an epicentral area after an explosion. Zones with irreversibly changed mechanical and filtrational parameters of geological media are compared with a spatiotemporal distribution of high-amplitude aftershocks in plan and cross-sectional views. The cone of depression formed in the potentiometric surface coincides with the area of registered microseismic events. The general trend of decreasing microseismicity intensity induced by underground large-scale explosion is synchronic with stabilization of the hydrogeodynamic situation.

本文介绍了在塞米巴拉金斯克试验场内的物体大规模爆炸之前和之后进行的地质，结构和水文地质调查的结果。将获得的数据与爆炸后震中区域记录的余震排放的公开信息进行比较。在平面图和横断面图中，将地质介质的机械和过滤参数不可逆地变化的区域与高振幅余震的时空分布进行了比较。电位计表面中形成的凹陷锥与已记录的微地震事件的区域重合。地下大规模爆炸引起的微震强度降低的总体趋势与水文地质动力状况的稳定是同步的。
