Abstract
This article presents the results of seismic process studies in the territories adjacent to the essential facilities of the Far East. It shows the possibility for a reasonable description of the epicenter vector during prediction seismic impacts on extended objects.
Highlights
Rational ground of engineering solutions in seismic areas requires a quantitative description of seismicity
According to the Set of Rules 14.13330.2014 [5] in construction design for seismic areas the materials and structural design providing the lowest value of earthquake loads have to be applied
Works on seismic microzonation made by instrumental methods which goal is to divide an area into parts with different expected intensity of reaction to seismic impact should precede any design
Summary
Rational ground of engineering solutions in seismic areas requires a quantitative description of seismicity This description should correspond to the ways of its continued use: in some cases it is necessary to provide simultaneous prediction for expected intensity in different places, in other cases - independent evaluations of possible earthquake impacts in each considered area will be sufficient. Besides nearsurface geological conditions it is necessary to mention that peak ground reactions and constructions are influenced by nature of an oncoming seismic signal as well Such parameters as vector of seismic waves, amount of seismic energy released at depth, its scattering on crustal heterogeneity influence directly on frequency, amplitude and duration of seismic effect. Thereby, besides experimental researches directly on the object it is necessary to study characteristics of seismic process of the territories adjoined to an object and region in general
