Seismic Waves There are two basic types of seismic waves: body waveswhich travel through the body of the earth and sur- face waveswhich travel around the surface of the earth. S-waves, or secondary waves travel more slowly than P waves. (skin-effect) represent another type of surface waves. <>
Earthquakes generate four principal types of elastic waves; two, known as body waves, travel within the Earth, whereas the other two, called surface stream

Compressional, Primary, Longitudinal Alternating compressions (“pushes”) and dilations (“pulls”) which are directed in the same direction as the wave is propagating (along the raypath) P motion travels fastest in materials, so the P-wave is the first- arriving energy on a seismogram. This wave behaviour can also be used on a smaller scale by recording waves generated by explosions or ground vibrators in the search for oil and gas.

The first type of body wave is the P wave or primary wave. P waves act like an accordion, and move parallel to the propagation direction. Characteristics-1 As the wave moves towards it, the rock is tremble in parallel to it, it is known as a longitudinal wave.2. P waves in a liquid or gas are pressure waves, including sound waves. waves. : 48–50: 56–57 Other modes of wave propagation exist than those described in this article; though of comparatively minor importance for earth-borne waves, they are important in the case of asteroseismology.

The two main types of waves are body waves and surface waves. by mapping seismic gaps, scientists can identify which areas are most at risk within a timeframe of 30 to 100 years 3. There are three basic types of seismic waves – P-waves, S-waves and surface waves. This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station. %����

In this lesson, we discussed four types of seismic waves: P-waves, S-waves, Rayleigh waves and Love waves. (slide 12) Rayleigh waves are another type of surface wave. Analogously, surface elastic waves can propagate along the surface of an elastic substance. The first type of body wave is the P wave or primary wave. L- Waves… <>
The P-wave is the "fast" wave and can be called a push-pull wave, because it moves by contracting and ex-panding along a horizontal path . Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Seismic waves can be defined as, “the waves of energy caused by the sudden breaking of rock within the earth or an explosion”1. In these waves the particles vibrate at … 1 0 obj
