NettetEarthquakes cause vibration waves to travel through the ground. The first sign of a quake is often the rumbling sound caused by the ‘P’ (primary or push) waves. These travel at about 20,000 kilometres an hour. That is twenty times faster than a jet plane. The ‘S’ (secondary or shear) waves follow along at about 10,000 kilometres an hour.
