Theoretical probability of resonance is tested against experimental seismic measurements in a layer of frozen coarse sediments overlying frozen bedrock. Resonance frequencies are estimated relative to the frequencies of P and S waves from 14 earthquakes recorded at three stations. P and S velocities in the sediments are predicted proceeding from the equality of resonance frequency/velocity ratios using integrate values of water content- and temperature-dependent velocities in sedimentary frozen ground in the Baikal and Transbaikal regions. Thus seismic velocities in unconsolidated sediments can be predicted from earthquake records using integrate laboratory and field velocity data.
