WebDec 13, 2024 · P-wave velocity in earthquakes is 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 13.5 km/s in the lower mantle, and 11 km/s through the inner core. We usually say that the speed of sound waves depends on density. WebAn earthquakes first P-wave arrives at a seismic station at 12:00:00. This P-wave has traveled 6000 kilometers from the epicenter.
