how is the fact that p waves travel more quickly than s waves used to detirmine the distance of an earthquake’s epicenter from a seismograph station?
Chosen Answer:
P-waves are a type of elastic wave, also called seismic waves, that can travel through gases (as sound waves), solids and liquids, including the Earth. P-waves are produced by earthquakes and recorded by seismographs. The name P-wave stands either for primary wave, as it has the highest velocity and is therefore the first to be recorded; or pressure wave. (…and S-waves or shear waves cannot pass through liquids as P-waves can.)
