I can provide you with some information.
Earthquakes are caused by the sudden release of energy in the Earth's crust, typically due to tectonic plate movements. The sound associated with an earthquake can vary depending on several factors, such as the magnitude of the earthquake, the depth at which it occurs, and the distance from the epicenter.
In general, people close to the epicenter of an earthquake often report hearing a variety of sounds before and during the event. These sounds can include rumbling or low-frequency noises, similar to the sound of thunder or a passing train. Some describe it as a deep growling or roaring sound. However, it's important to note that not everyone will hear these sounds, as they may be masked by other environmental noises or may not be audible depending on the circumstances.
It's worth mentioning that earthquake sounds travel through the ground rather than through the air, so they are typically perceived as vibrations by humans rather than as distinct sounds. These vibrations can be detected by seismographs and other sensitive instruments, which are used to measure and analyze earthquakes.
Keep in mind that the experience of an earthquake can vary widely depending on the individual's proximity to the epicenter and the specific characteristics of the earthquake itself.
