This letter discusses the results of microseismic oscillations’ recording in the “voice of the sea” range (5–10 Hz), generated jointly by wind waves and the wind during the passage of typhoons in the Sea of Japan. Amplitude-time dependence of these infrasonic oscillations’ variations is investigated, with account for their energy characteristics, determined on the laser-interference measuring complex data. As a result of accounting for the directional diagrams of the measuring devices, comparing the data obtained with satellite imagery and model data on the atmosphere surface layer, we determined the areas of signal generation in accordance with the change in the typhoons’ vortex components. The length of these areas is up to 300 km.
