No, but P and S waves are used for earthquakes..and everybody should know that p waves come befoe s waves during an earthquake and maybe even during an aftershock....

They go faster through the inner core than the liquid outer core.
S-waves (or Secondary waves) and Love waves are both transverse seismic waves.
A seismograph is an instrument that measures the seismic wave activity in an area. According to Wikipedia, Seismometersare instruments that measure and record motions of the ground, including those of seismic waves generated by earthquakes, nuclear explosions, and other seismic sources. Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources. A seismic wave, according to wikipedia is, "Seismic waves are waves of force that travel through the Earth or other elastic body, for example as the result of an earthquake, explosion, or some other process that imparts forces to the body. Seismic waves are also continually excited on Earth by the incessant pounding of ocean waves (referred to as the microseism) and the wind."Seismograph is another Greek term from seismós and γράφω, gráphō, to draw. It is often used to mean seismometer, though it is more applicable to the older instruments in which the measuring and recording of ground motion were combined than to modern systems, in which these functions are separated. Both types provide a continuous record of ground motion; this distinguishes them from seismoscopes, which merely indicate that motion has occurred, perhaps with some simple measure of how large it was.
Firstly, there are 3 types of seismic waves. Long Waves, Primary Waves(Longitudinal) and Secondary Waves(Transverse). Long Waves travel quickly along the Earth's crust, the thin outer layer. Primary Waves are longitudinal waves, they can travel both through solids andliquids, so they travel through the crust, the mantle, and the outer core (note that they refract through each layer, as each layer has a different density. Secondary Waves are transverse waves, they can only travel through solids, so they go through the inner and outer mantles, and curve away from the cores.

none, p-waves can travel anywhere
The Crust of the Earth
The liquid outer core of the Earth's interior refracts p-waves at the boundary with the mantle, and does not carry s-waves.
P' waves and 'S' waves are both seismic waves that travel through the Earth. 'S'waves are unable to go through any liquid. 'P' waves, on the other hand, can go through both solids and liquids.

Both waves travel along Earth's surface and decrease in amplitude with depth below the surface.

We use seismic waves (or pressure waves) to interpret the internal structure of both the sun and earth. When studying the sun it is called helioseismology on earth it is just called seismology
Earthquakes are made up of 4 different seismic waves, P, S, L and R. L and R are surface waves, and have virtually nothing to do with the interior. However, P and S are body waves and do. P waves are compressional waves, that is they push and pull against rock in the same direction as the waves move. They are the fastest. S waves vibrate material up and down. Both travel faster in more dense material, and P waves travel slower in liquid while S waves are unable to move through liquid at all. As the Earth's outer core is liquid, and inner core is very dense, this affects the waves as they travel through the Earth. It speeds them up and slows them down according to the density. Because S can't go through the outer core, there is a "shadow zone" at a certain area on the Earth where there are no S waves at all. P waves also have a smaller shadow zone, where the waves are diflected and bent within the outer core.
