• Various natural phenomenon such as Avalanches, volcanoes, earthquakes, ocean waves, water falls and meteors also generate infrasonic waves

• Even the human body can generate mechanical vibrations at very low frequencies, which are known as the  infrasonic waves. Such low-frequency vibrations/infrasonic waves  are produced by physiological processes—such as heartbeats, respiratory movements, blood flow in vessels, and other processes.
