Abstract—Numerical modeling of induced seismicity resulting from fluid injection into the subsurface is considered. One of important factors determining the slip dynamics of a tectonic fault during fluid injection loading is the form of the law of friction acting on the fault sides. The numerical analysis in the context of a slider model compared t...

AbstractThe paper presents the results of modeling the stress–strain state of the epicentral zone of the strong crustal Hanshin–Awaji earthquake, which occurred in the area of Kobe (Japan) on January 17, 1995, with a magnitude M of 6.9. In this work the author’s method for modelling and analyzing the stress–strain state of the epicentral zones of c...

AbstractWe examine the formation conditions for the resources and chemical composition of mineral lakes located in the vicinities to the unique natural site of the Barguzin intermontane depression, Nizhnii Kuitun. Presented are the results from studying the surface structure of this sand massif. It is shown that its formation is associated with pec...

AbstractMacroseismic and instrumental data on the January 8, 2018, Muong Ang earthquake in northwestern Vietnam are comparatively analyzed. Good agreement is found between the macroseismic and instrumental data, which in turn correlate perfectly with the tectonic data. The Muong Ang earthquake consisted of foreshocks, the mainshock, and three serie...
Underground gas storage facilities are an important element of the natural gas supply system. They compensate for seasonal fluctuations in natural gas consumption. Their expected lifetime is in tens of years. Continuous monitoring of underground gas storage is therefore very important to ensure its longevity. Periodic injection and withdrawal of na...

The ratio of P- to S-wave velocities, VP/VS, is an important parameter characterizing rock composition and fluid saturation. We have studied properties of the ratio in the West-Bohemian seismically active region, using data from the earthquake swarm which occurred here in 2008. The earthquake swarm was well recorded by 23 seismic stations from epic...

The results of numerical calculations for the deformations of radially heterogeneous and imperfectly elastic medium during sliding on a fault specified by an arbitrarily oriented fault plane and the dislocation vector tangential to this plane are presented. The implications of the rheology of the medium for the pattern of surface deformations after...

Based on recent experimental and theoretical model results, the role of earthquakes and processes of their preparation as electricity sources in the global electric circuit (GEC) is discussed. In addition to the traditional elements of the GEC, such as thunderstorm currents, ionosphere currents, fair weather currents, and telluric currents, hypothe...
