A skyquake is a phenomenon where a loud sound is reported to originate from the sky. It often manifests as a banging, or a horn-like noise. It often manifests as a banging, or a horn-like noise. The sound may cause noticeable vibration in the ceiling or across a particular room.
Acoustic sources within the "jet pipe" also contribute to the noise, mainly at lower speeds, which include combustion noise, and sounds produced by interactions of a turbulent stream with fans, compressors, and turbine systems. [1] The jet mixing sound is created by the turbulent mixing of a jet with the ambient fluid, in most cases, air.
Videos of eerie noises erupting from the skies have recently surfaced on YouTube, sending people into a panic around the world. The video above shows a particularly frightening episode of this ...

Often, it is first noticed some seconds after the direct noise of the passing aircraft has diminished. The sound then gets louder. Nevertheless, being highly directional, wake turbulence sound is easily perceived as originating a considerable distance behind the aircraft, its apparent source moving across the sky just as the aircraft did.
The pictures above demonstrate the still amazing visual effects that occur as military aircraft punch through the sound barrier and travel faster than sound itself. More from Business Insider:
Explaining their discovery in 2005 of a powerful bursting radio source, NRL astronomer Dr. Joseph Lazio stated: [23] "Amazingly, even though the sky is known to be full of transient objects emitting at X- and gamma-ray wavelengths, very little has been done to look for radio bursts, which are often easier for astronomical objects to produce ...
