Definition of Subterranean rumbling
Subterranean rumbling is a phenomenon in which the ground vibrates and makes sounds due to an earthquake.
During earthquakes or volcanic eruptions, the ground vibrates, sometimes creating short-period seismic wave motion (ground motion) that reaches the air and becomes sounds (sound waves), and low sounds can be heard.
This often occurs during shallow-focus earthquakes and earthquake swarms. Even microearthquakes that produce noticeable tremors can sometimes produce rumbling.
