The Bachat earthquake that occurred in Kemerovo oblast on June 18, 2013 with a local magnitude of ML = 6.1 is the strongest in a series of events in the vicinity of an open-pit mine of the same name, as well as the world’s largest technogenic earthquake in the extraction of solid minerals. Research on the seismicity in the environs of the mine using local networks of temporary stations began several years prior to the earthquake and continues today. We present the results of this research. Particular attention is given to monitoring of the seismic regime of technogenic activation of the Bachat coal mine and its nature. 相似文献

This work determines the parameters of the meteoroid that exploded in Chelyabinsk oblast on February 15, 2013. Using video observation and automobile registration cameras, we identified the trajectory and velocity of the meteoric body from the beginning of its glow to the destruction. The precise explosion time (03:20:34UTC) was determined on the basis of records of the broadband seismic stations and arrivals of the surface wave. The estimated explosion energy with assumption of a point source similar to a high thermonuclear explosion was 100 kt in TNT equivalent based on the surface wave amplitude. The archive of records of seismic stations during the meteorite flight is composed. 相似文献

Study of the sections of Neopleistocene–Holocene deposits filling the basins in central Gorny Altai has revealed earthquake-induced soft-sediment deformation (seismites). They formed as a result of the brittle deformation of deposits and liquefaction of loose water-saturated sediments under vibration seismic impact. The paleoearthquakes resulting in such seismites had the minimum intensity I = 6 and magnitude M = 5–6. Hence, the study region underwent strong earthquakes in the Neopleistocene–Holocene. 相似文献

The stress state of the Earth’s crust in the region of the Chuya earthquake of 2003 (Gorny Altay) is studied using the data of long-term epicentral observations by dense networks of temporary stations. These data comprise 545 seismic events, which widely vary in energies and whose parameters are determined highly accurately. Two hierarchical levels of the stress field are revealed and their spatial structure and temporal behavior are investigated. It is shown that the subregional stress field, which is determined from the data on strong earthquakes, is predominantly stable across the studied area, where the regime of horizontal shear with submeridional orientation of principal pressure axes is observed. The local stress field calculated from the weak seismic events experiences regular variations, which are consistent with the block structure of the crust; this field is heightand time-dependent. 相似文献

The co-seismic deformations produced during the September 27, 2003 Chuya earthquake (Ms = 7.5) that affected the Gorny Altai, Russia, are described and discussed along a 30 km long segment. The co-seismic deformations have manifested themselves both in unconsolidated sediments as R- and R′-shears, extension fractures and contraction structures, and in bedrock as the reactivation of preexisting schistosity zones and individual fractures, as well as development of new ruptures and coarse crushing zones. It has been established that the pattern of earthquake ruptures represents a typical fault zone trending NW–SE with a width reaching 4–5 km and a dextral strike–slip kinematics. The initial stress field that produced the whole structural pattern of co-seismic deformations during the Chuya earthquake, is associated with a transcurrent regime with a NNW–SSE, almost N–S, trending of compressional stress axis (σ1), and a ENE–WSW, almost E–W, trending of tensional stress axis (σ3). The state of stress in the newly-formed fault zone is relatively uniform. The local stress variations are expressed in insignificant deviation of σ1 from N–S to NW–SE or NE–SW, in short-term fluctuations of relative stress values in keeping their spatial orientations, or in a local increase of the plunge angle of the σ1. The geometry of the fault zone associated with the Chuya earthquake has been compared with the mechanical model of fracturing in large continental fault zones with dextral strike–slip kinematics. It is apparent that the observed fracture pattern corresponds to the late disjunctive stage of faulting when the master fault is not fully developed but its segments are already clearly defined. It has been shown that fracturing in widely different rocks follows the common laws of the deformation of solid bodies, even close to the Earth surface, and with high rates of movements. 相似文献
