Body Waves. Primary waves (P-waves) and secondary waves (S-waves) are the two types of body waves (Figure below). On the other hand, surface waves propagate only at the interface between two different media, like the interface between Earth and atmosphere (i.e. P waves, S waves, and Surface waves. Surface wave arrives after body waves due to the fact that they only travel through crust. The main types of seismic waves: P, S, and surface waves Seismic waves can either be body waves or surface waves -- but the full story is far more complex.

So we can say that Primary waves plot first on the seismograph and after 1.7 seconds S- waves will plot. Surface waves are typically generated when the source of the earthquake is close to the Earth’s surface. Although they move even more slowly than S-waves, they can be much larger in amplitude and are often the most destructive type of seismic wave. There are two types of body waves: P-waves and S-waves. Body wave definition, a transverse or longitudinal earthquake wave that travels through the interior of the earth (distinguished from surface wave). These seismic waves produce a long wave on the seismographs. Based on the medium they travel in, earthquake waves can be classified under two categories: Body waves; Surface waves; Body waves are those waves that travel through the earth. When an elastic body, such as a rock is struck with a blow, two types of elastic waves are produced and these waves travel out from the source. Seismic waves are like those ripples which can travel through the inside of the earth, as well as on the surface. Difference between P and S- waves:-We can easily recognize P & S waves on seismograph because the velocity of P- waves is 1.7 times more than the velocity of the S- waves. Which type of seismic wave arrives after body waves due to the fact that they only travel through crust? The P in P-waves stands for primary, because these are the fastest seismic waves and are the first to be detected once an earthquake has occurred. As their name suggests, surface waves travel just below the surface of the ground. Seismic Body-wave Traveltime Tomography Tutorials. In an earthquake, body waves are responsible for the sharp jolts. by Mihai Andrei. The first type of wave is exactly the same in its physical properties as a sound wave. The types of waves that are useful for understanding Earth’s interior are called body waves, meaning that, unlike the surface waves on the ocean, they are transmitted through Earth materials. Body waves travel through the interior of the earth. See more. the surface of the Earth). The shaking we experience is the vibration of the elastic rocks by the energy in seismic waves. Body waves move at different speeds through different materials. Figure 9.1.1 Hitting a large block of rock with a heavy hammer will create seismic waves within the rock. Body waves are of two types: Primary waves (also called P-waves, or pressure waves) and Secondary waves (S-waves, or shear waves). Body waves travel through the interior of the Earth. s.
