The statistical evaluation of the H/V ratio of microseismic oscillations for determining the geotechnical properties of upper geological layer is proposed. Measurements have been carried out for different types of grounds and a good agreement of the results with its values of shear wave velocity is demonstrated. The proposed method is based on the usage of ultralow noise density 3-axis MEMS accelerometer, thus making the equipment very small and portable.
