On the assessment of the modified Schwarz‘s algorithm convergence in VEZ direct problem

(Spassky B.A. Yudin M.N. )

Some obstacles in the solution of electrical sounding (VES) forward problem with using modified Schwartz method are considered in the paper. It is shown, that class of the models, when this iteration process is convergence, is limited. It's scheduled the ways of significant extension this class elements. Convergence of successive approximations to the solution was confirmed by computational experiments results.......

Application of ground-underground gravity survey at Verkhnekamsky potash deposit

(Bychkov S.G. Prostolupov G.V. Shcherbinina G.P. )

We consider the data interpretation technology ground-underground gravity survey in solving problems of safe operation of the potash mines. We describe the pre-packages of the method, data processing technology. It is shown that modern methods of processing and interpretation of ground-underground gravity data significantly increase the information content of geophysical researches and can successfully identify high-risk areas when developing reservoirs.......

Macroseismic anisotropy of earthquake at the Middle Urals 18th October 2015

(Dyagilev R.A. Verkholantsev Ph.G. Guseva N.S. )

On October 18, 2015 at 21:44:55 (GMT) an earthquake with a magnitude M 4.7 had happened at the Middle Urals. It had been sensed over a wide area in the Sverdlovsk and Perm region. The article presents the analysis of macroseismic data, collected after event. Variants of representation of intensity field concerning anisotropic components are shown.......

Earth crust tectonics at the Perm region territory by gravimetry and magnetometry data

(Tarantin M.V. Kostitsyn V.I. Prostolupov G.V. Chadaev M.S. Gershanok V.A. Iblaminov R.G. )

The paper is devoted to the problem of earth crust structure refining, characteristics of relation of Moho depth and global tectonic structures of sediment cover and crystal basement and local structures distribution features. For data processing gravity and magnetic maps of scale 1:1 000 000 are used. Inversion of the data involves schematic map of Moho boundary «Crustal Structure Maps of Europe», composed by European Seismological Commission (Warsaw, Helsinki, 2007). During the processing of geophysical surveys we used parametric relations of considered Earth fields.......
