I stumbled across an interesting subject online http://boards.straightdope.com/sdmb/showthread.php?t=449378 Leads me to wonder what the fastest terrestrial sound conduction speed is.
https://en.wikipedia.org/wiki/P-wave P-waves from earthquakes are very low frequency sound waves.Typical values for P-wave velocity in earthquakes are in the range 5 to 8 km/s. The precise speed varies according to the region of the Earth's interior, from less than 6 km/s in the Earth's crust to 13 km/s through the core.

The velocity of sound has a very simple functional form:jim mcnamara said:https://en.wikipedia.org/wiki/P-wave P-waves from earthquakes are very low frequency sound waves.
Sound waves are in fact compression waves: http://www.physicsclassroom.com/class/sound/Lesson-1/Sound-is-a-Pressure-Wave

The fastest terrestrial sound conduction speed refers to the maximum speed at which sound can travel through a solid material on land.
The fastest terrestrial sound conduction speed ever recorded was 18,000 meters per second, which was achieved in a diamond.
The speed of sound conduction in solids is affected by factors such as the material's density, elasticity, and temperature. Materials with higher density and elasticity tend to have faster sound conduction speeds, while higher temperatures can increase the speed of sound.
The speed of sound conduction in solids is generally faster than in liquids and gases. However, some liquids and gases, such as water and helium, can have faster sound conduction speeds than certain solids.
Understanding the fastest terrestrial sound conduction speed can have practical applications in fields such as materials science, engineering, and acoustics. It can help in the development of new materials for sound insulation or improved communication technologies. It can also aid in the detection and monitoring of earthquakes, as well as in medical imaging techniques such as ultrasound.
