Numerical modeling using the semblance parameter has demonstrated high efficiency and noise immunity of emission tomography in reconstructing the spatial distribution of small seismic sources in the crust at single-component acquisition. High noise of additive (low signal/noise ratio) and parametric (lateral inhomogeneities) origin deteriorates the quality of source imaging but does not rule out the possibility to create the image. The modeling implies signals limited within a certain estimated frequency bandwidth.
