## What are the three types of earthquake 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.

## What are the three major seismic waves that are interested during an earthquake?

Three types of seismic waves are generated as a result of earthquakes:

• P (primary) waves.
• S (secondary) waves.
• Surface waves, which arrive simultaneously at seismic recording stations.

## What are P and S seismic waves?

In P or compressional waves, the vibration of the rock is in the direction of propagation. 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.

## What is the difference of P wave and S wave?

P waves travel at speeds between 1 and 14 km per second, while S waves travel significantly slower, between 1 and 8 km per second. The S waves are the second wave to reach a seismic station measuring a disturbance. The difference in arrival times helps geologists determine the location of the earthquake.

Surface waves

## Which seismic waves are responsible for the greatest damage to human structures?

Seismic waves can be classified into two basic types: body waves which travel through the Earth and surface waves, which travel along the Earth’s surface. Those waves that are the most destructive are the surface waves which generally have the strongest vibration.

## What type of earthquake wave causes the greatest damage quizlet?

Primary waves travel in a push/pull or compression/expansion type of motion, while secondary wave travel in as transverse waves in an up/down type of motion. Surface waves make the rock particles travel in a circle/elliptical motion. Of all the three waves, surface waves cause the most damage.

## Why surface waves cause the most damage to property?

Surface waves are slower than body waves. It is the surface waves which cause most property damage because surface waves produce more ground movement and travel more slowly, so they take longer to pass.

P-waves

## How do you know which wave has the highest energy?

(b) The wave with the shortest wavelength has the greatest number of wavelengths per unit time (i.e., the highest frequency). If two waves have the same frequency and speed, the one with the greater amplitude has the higher energy.
