Which type of waves is produced by sources of bigger size such as earthquakes, ocean waves and volcanic eruptions?

Infrasonic, vibrational or stress waves in elastic media, having a frequency below those of sound waves that can be detected by the human ear—i.e., below 20 hertz. In nature such waves occur in earthquakes, waterfalls, ocean waves, volcanoes, and a variety of atmospheric phenomena such as wind, thunder, and weather patterns.
