Determining the Positions of Seismically Active Faults in Platform Regions Based on the Integrated Profile Observations
- 9 Downloads
By the examples of the Roslavl’skii, Grafskii, and Platava–Varvarinskii faults, the possibility is demonstrated of mapping the geological objects by the measurement algorithm that includes successively measuring the spectra of microseisms at the points of the measurement network by movable instruments and statistical accumulation of the ratios of the power spectra of the amplitudes. Based on this technique, the positions of these seismically active faults are determined by the integrated profile observations of the parameters of microseismic and radon fields. The refined positions of the faults can be used in estimating the seismic impacts on the critical objects in the vicinity of these faults.
