WebThere are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. P waves cause the ground … WebSecondary, or S, waves travel more slowly. As S waves have a greater amplitude than P waves the two groups are easily distinguishable on the seismogram. By measuring the time interval between the arrivals of the P and S wave groups seismologists are able to calculate the distance between the seismograph and the origin of the earthquake.

Webc. What is the difference between S waves and P waves? P (primary) waves, which are similar to sound waves, come first. The S (secondary) waves, which are a type of shear wave, come second. Within the Earth, P waves can travel through solids and liquids, whereas S waves can only travel through solids. 5. WebPrimary waves (or P waves) are the fastest moving waves, traveling at 1 to 5 miles per second (1.6 to 8 kilometers per second). They can pass through solids, liquids and gases easily. As they travel through rock, the waves move tiny rock particles back and forth -- pushing them apart and then back together -- in line with the direction the wave is traveling.

WebS Waves, known as Secondary Waves, are seismic waves that simply go about in an S shape, form, and is the second wave to arrive during an earthquake. S waves cannot travel through liquids, they can travel through solids. P waves, known as Primary waves, are also part of a seismic wave. This waves comes first during an earthquake, it is the ... WebThe first kind of body wave is the P wave or primary wave. It’s the fastest kind of seismic wave, and the first to arrive at a seismic station.
