Other articles where Primary wave is discussed: earthquake: Principal types of seismic waves: The P seismic waves travel as elastic motions at the highest speeds. They are longitudinal waves that can be transmitted by both solid and liquid materials in the Earth’s interior. With P waves, the particles of the medium vibrate in a manner similar to sound waves—the…
ADVERTISEMENTS: After reading this article you will learn about primary, secondary and surface seismic waves. Wave motion is a familiar motion observed by us. When a stone is thrown into a pool, the water surface is disturbed where the stone strikes and ripples move outward from the point of disturbance. This train of waves is […]
A P-wave is one of the two main types of elastic body waves, called seismic waves in seismology. P-waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph.P-waves may be transmitted through gases, liquids, or solids.
For example, like the start-ups of the primary wave of Internet, discoveries and progress were achieved by liberal and marginal youth, that were not primarily motivated by financial gains, and the model of concentrating the e-industry in one place that some Arab countries think of adopting, is now abandoned where it originated
P Waves are primary waves. Introduction P waves are produced by all earthquakes. They are compression waves that form when rocks break due to pressure in the Earth. S waves are secondary waves that are also created during an earthquake. They travel at a slower speed than the p-waves.
Types of seismic waves. There are three basic types of seismic waves – P-waves, S-waves and surface waves. P-waves and S-waves are sometimes collectively called body waves. P-waves. P-waves, also known as primary waves or pressure waves, travel at the greatest velocity through the Earth.
Primary Waves P Waves & S waves. Primary waves (p waves) are the first earthquake waves to reach reporting stations. Today, there are about 4000 reporting stations worldwide. The USGS estimates there are several million earthquakes that occur each year. Most are undetected because of their remote locations.

P waves, also called compressional or longitudinal waves, give the transmitting medium—whether liquid, solid, or gas—a back-and-forth motion in the direction of the path of propagation, thus stretching or compressing the medium as the wave passes any one point in a…
Primary waves (P-waves) are compressional waves that are longitudinal in nature. P waves are pressure waves that travel faster than other waves through the earth to arrive at seismograph stations first, hence the name "Primary". These waves can travel through any type of material, including fluids, and can travel nearly 1.7 times faster than ...
