ON THE ESTIMATION OF THE MICROSEISMIC SOUNDING METHOD ACCURACY

V.V. Pupatenko

Аннотация


In this paper, the author considers the necessity of the microseismic soundingmethod (MSM)and possible approaches to  estimation of its accuracy. The MSM method is a passive amplitude method for seismic tomography in which spatial variations in Rayleigh wave amplitudes are associated with variations in shear wave velocities.  Two statistical methods for estimating the accuracy of the values given on the high-speed sections of the MSM method are discussed.
