Quantitative Estimation of How Variations in Near-Bottom Pressure Are Transformed into Microseismic Oscillations of Upper Crust in the Frequency Range of Wind Waves

This paper presents quantitative estimate of the influence of near-bottom pressure due to wind waves and sea swell on the upper crustal layer based on data recorded by a laser meter of hydrosphere pressure variations and by two laser strainmeters. The processing and analysis of these data revealed that the coefficient expressing the transformation of near-bottom pressure in the shelf area of the Japan Sea due to marine wave processes into elastic oscillations of the crust is dependent on the periods of progressive sea waves.
