Earth hums because of ocean waves

Earth Background Noise

Even without earthquakes, seismometers constantly record seismic energy. It records periods of oscillations about every 6 seconds as background noise.

These oscillations are due to ocean waves constantly crashing into continents. Land masses shake back and forth like a metronome.

And during storms, it worsens as the reverberations are amplified.
