Main results of the Project.

To solve the project tasks the complex of modern methods based on seismic data analysis has been applied.

The following methods were used for Q-factor determination:

  • determination of Q-factor on the grounds of code waves study of certain seismic station, based on the model of single scattering of volume waves;
  • determination of Q-factor based on the spectral relations of two seismic stations;
  • construction of damping field based on tomographic inversion method, as well as seismic tomography method to determine the seismic waves rates, which were used in calculating the damping field.

To construct the focal spectrum for further computation the dynamic parameters of focal point, a modern approach to modelling inversion was applied taking into account the Green function (attenuation function and station corrections).

 

A method based on the spectral relation of horizontal component to vertical one (Nakamura Y. A.) was applied to calculate station corrections. The wave inversion method was applied to calculate the seismic moment tensor, and the method based on the signs of the first entries of seismic waves was used to calculate the focal mechanisms. During the reconstruction of stresses according to the field data collected in 2015 and 2017, the cataclastic analysis method of Yu.L. Rebetsky and O. I. Gushchenko was applied. The method of seismotectonic deformations of S. L. Jung was applied in the stress-strain state study. The following programs were developed to effectively solve the problems of the Project:

  • Software for Q-factor determination on the grounds of code waves analysis.
  • Software for Q-factor determination on the grounds of spectral relations of two seismic stations;
  • Software for construction of damping field by the tomographic inversion method;
  • Software for station corrections calculation based on spectral H/V relation; software for calculation of station spectrum;
  • Software for focal spectrum calculation and determination of their characteristics.

Project Title:  Study of Modern Geodynamic Processes of Seismic Regions using Magnetotelluric Sounding Methods (by the example of Tien Shan)   

Project Manager:  Anatoly K. Rybin

Project Period: 2017 – 2019 

RFBR Project №17-05-00844 Report for 2018

 

Main Results of the Project in 2017

The purpose of the project is to solve the fundamental problem of the Earth studies – the problem of studying modern geodynamic processes in a wide range of phenomena – from disastrous (earthquakes, landslides, karst formation etc.) to virtually unnoticeable changes of stressed and deformed state of geologic environment. These processes become apparent in different physical fields and physical parameters including electromagnetic fields and electromagnetic parameters of lithosphere. To create tools of electromagnetic monitoring of modern geodynamic processes, the Project involves the solution of a number of theoretical and practical tasks within the scope of development of new approach to processing of magnetotelluric sounding data (MTS) to single out endogenous electromagnetic fields.

On the basis of analytical solution found for the direct problem of MTS using continuation of a field, we suggested an approach according to which endogenous electromagnetic field enters into impedance relations by an additive way. Such linear relation allows distinguishing the electromagnetic field recorded at daylight surface by the position of sources. The main idea of algorithm is that using the known impedance of lower half-space we need to find the difference of tangent components of electromagnetic field recorded at daylight surface. For implementation of this algorithm, we developed the MTS data processing program to single out the sources of endogenous electromagnetic field.

Project Title: “Methodological Basis for Assessment of Stressed and
Deformed State of Geologic Environment According to the Results of
Electromagnetic Monitoring of Seismic Regions”

Project Manager: Elena A. Bataleva

Project Period: 2017 – 2019

RFBR Project № 17-05-00654а Report for 2018

List of publications for 2018

Results of the Project № 17-05-00654а in 2017

The most promising for the monitoring of geodynamic processes is the use of electromagnetic sounding methods which ensure effective observations of changes in the physical properties of the Earth’s lithosphere due to their technological effectiveness. This project is aimed at development of methodological basis for assessment of stressed and deformed state of the Earth’s crust and its anisotropic properties. The analysis and interpretation have involved both advanced Russian methods and technologies of electromagnetic monitoring data analysis and interpretation, and theirwidely accepted world analogues as well as the software developed at Research Station RAS and Trofimuk Institute of Petroleum Geology and Geophysics of Siberian Branch of Russian Academy of Sciences (IPGG SB RAS) which was tested on a large volume of experimental data and is mainly directed to optimizationandwaysof visual interpretation of electromagnetic experiment results.

In 2017, the staff of GPS laboratory has fulfilled the planned scope of field geodetic observations except for some cases when weather conditions or other objective conditions made it impossible to conduct measurements.

From May to August 2017, we conducted 2 campaigns to measure regional sites at the territory of Kyrgyzstan (fig.1). The regional GPS campaigns involved four field teams including the operator and the driver of ZIL-131 truck. During one month, each team can measure up to 14-15 sites (36 hours for one site). The trucks have travelled 1466-2836 km, ~ 1860 on average.
