Abstract


A performance of the algorithm of emission tomography based on nonlinear beamforming in a strong signal decorrelation presence is shown with use of the seismic data recorded by Kirghiz broadband net (KNET). Brightness distribution of an image of the upper part of the Earth's crust corresponds to the ridge relief. The system of narrow vertical inhomogeneitis interpreted as very fluid-permeable channels was revealed in the crust-mantle gray area.

Key words


Emission tomography, passive monitoring, seismic noise
