What are the different types of earthquake waves explain?

Earthquakes generate three types of seismic waves: P (primary) waves, S (secondary) waves and surface waves, which arrive at seismic recording stations one after another. Both P and S waves penetrate the interior of the Earth while surface waves do not. Due to this, P and S waves are known as “body waves”.

What are P waves or longitudinal 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…

What are the types of earthquake waves Class 11?

(i) ‘P’ or longitudinal waves or primary waves – These waves travel in the direction of their movement. They can travel through solid as well as liquid matter. (ii) ‘S’ or transverse or secondary waves – These waves travel at right angle to the direction of their oscillation.

What are the types of waves in geography?

There are two different types of wave – constructive and destructive. They can affect the coastline in different ways. When a wave reaches the shore, the water that rushes up the beach is known as the swash .

What is AP wave in an earthquake?

A P wave, or compressional wave, is a seismic body wave that shakes the ground back and forth in the same direction and the opposite direction as the direction the wave is moving.

What are the P and S waves collectively called?

Taken collectively, p- and s-waves are known as “body” waves. The velocities of both can be measured via seismic refraction. Surface Waves, as the name implies, travel primarily along the ground surface; amplitudes decrease rapidly with depth. There are two types of surface waves.

What do you mean by earthquake explain the three earthquake waves?

An Earthquake is a sudden shaking of the Earth’s crust due to sudden release of energy. The three types of earthquake waves are:- p-wave, s-wave,surface wave. p-wave:- they are primary because they are fastest. s-wave:-they are secondary because they are slower. surface wave:-It is the seismic wave trap near the earth.

What are three types of waves generated by earthquakes?

Earthquakes generate three types of seismic waves: P (primary) waves, S (secondary) waves and surface waves, which arrive at seismic recording stations one after another. Both P and S waves penetrate the interior of the Earth while surface waves do not. Due to this, P and S waves are known as “body waves”.

What are the most destructive waves of an earthquake?

Surface waves are similar in nature to water waves and travel just under the Earth’s surface. They are typically generated when the source of the earthquake is close to the Earth’s surface. Although surface waves travel more slowly than S-waves, they can be much larger in amplitude and can be the most destructive type of seismic wave.

What are the strongest waves in an earthquake?

The two general types of vibrations produced by earthquakes are surface waves, which travel along the Earth’s surface, and body waves, which travel through the Earth. Surface waves usually have the strongest vibrations and probably cause most of the damage done by earthquakes. Body waves are of two types, compressional and shear.

What are the fastest waves from an earthquake?

P waves pass through gases, liquids and solids in the same manner. These waves travel outward from the point of disturbance in all directions in Straight lines. They are the fastest of all earthquake waves. Their average velocity is 5.3 km a second and a maximum of 10.6 km per second.
