# What are the three types of waves released during earthquake?

## What are the three types of waves released during earthquake?

There are three major kinds of seismic waves: P, S, and surface waves. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface.

## Which type of wave arrives first?

P waves
P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.

What type of seismic waves are released?

Earthquakes send out seismic energy as both body and surface waves. The body waves (P and S) and surface waves recorded by a seismometer.

### What kind of medium does a wave travel through?

-A disturbance that travels from one place to another transporting energy, but not necessarily matter, along with it. What is a medium? -It is the material through which a wave travels. Which type of waves require a medium? -Mechanical What are 3 types of mediums a mechanical wave can travel through? -Solids, liquids, and gasses.

### What kind of waves are generated by an earthquake?

The earthquakes generate waves on the surface of the earth and these are designated as seismic waves, these waves can be recorded by an apparatus called the seismograph.

How are body waves produced on the Earth?

Body waves are produced due to the discharge of energy at the focus and it progresses in all directions traveling through the body of the earth, hence, the name is body waves. When interacted with the surface rocks, these body waves generate a new collection of waves named “surface waves”. These waves travel along the surface.

## What are the two types of mechanical waves?

Mechanical Waves -waves that require a medium through which to travel Name two types of mechanical waves. -transverse and longitudinal Which type of wave moves in an up and down motion? -Transverse What type of wave moves parallel to the wave energy?
