# What are the slowest earthquake waves?

## What are the slowest earthquake waves?

The slowest (and latest to arrive on seismograms) are surface waves, such as the L wave. L waves are named for the Cambridge mathematician A.E.H. Love who first described them. The surface waves are generally the largest recorded from an earthquake.

## What are the slowest waves called?

The slowest body waves are secondary, or “S” waves. S waves are elastic shear waves that move material sideways, at right angles to their direction of travel. Because secondary waves travel only through solids, they do not penetrate the earth’s outer molten core. For this reason, there is also an S wave shadow-zone.

What are the 3 types of waves in an 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. A P wave is a sound wave traveling through rock.

What is P and S waves?

P waves can travel through solids, liquids, and even gases. S waves shake the ground in a shearing, or crosswise, motion that is perpendicular to the direction of travel. These are the shake waves that move the ground up and down or from side to side.

### What does the P stand for in P waves?

primary
Compressional waves are also called P-Waves, (P stands for “primary”) because they are always the first to arrive.

### What wave causes the most damage?

Surface waves
Answer and Explanation: Surface waves are the seismic waves that cause the most damage. Surface waves are named as such because they move along close to the surface of the Earth.

What happens to S and P waves as they travel inside Earth?

S waves cannot pass through the liquid outer core, but P waves can. The waves are refracted as they travel through the Earth due to a change in density of the medium. When the waves cross the boundary between two different layers, there is a sudden change in direction due to refraction. …

How do P waves and S waves move?

#### What is the relationship between S and 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.

#### Which is stronger P or S-waves?

S waves are more dangerous than P waves because they have greater amplitude and produce vertical and horizontal motion of the ground surface. The slowest waves, surface waves, arrive last. They travel only along the surface of the Earth.

What does S wave stand for?

secondary wave
The definition of an S wave, or secondary wave, is a wave motion in a solid medium where the medium moves perpendicular to the direction of the travel of the wave. An example of an S wave is when pieces of rock in an earthquake vibrate at right angles to the direction of the seismic wave.

Which is seismic wave type is most damaging?

Which seismic wave type is most damaging? 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. There are two basic kinds of surface waves: Rayleigh waves, also called ground roll, travel as ripples similar to those on the surface of water.

## Which is the slowest wave on the Earth?

The slowest waves, surface waves, arrive last. They travel only along the surface of the Earth. There are two types of surface waves: Love and Rayleigh waves. Love waves move back and forth horizontally. Rayleigh waves cause both vertical and horizontal ground motion.

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

Surface waves are one of four types of seismic waves generated during an earthquake. The four types of seismic waves present during an earthquake are primary waves, secondary waves, Rayleigh waves and Love waves. Rayleigh and Love waves are the two types of surface waves.

Which is more destructive P waves or S waves?

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. There are two basic kinds of surface waves: Rayleigh waves, also called ground roll, travel as ripples similar to those on the surface of water.
