Why Is It Called Love Wave?

Of the two surface seismic waves, Love waves—named

after the British seismologist A.E.H. Love, who first predicted their existence—travel faster

. They are propagated when the solid medium near the surface has varying vertical elastic properties.

What does love wave mean?

A Love wave is

a surface wave having a horizontal motion that is transverse (or perpendicular) to the direction the wave is traveling

What are Love waves called?

In seismology, Love waves (also known as

Q waves

(Quer: German for lateral)) are surface seismic waves that cause horizontal shifting of the Earth during an earthquake. … Love waves travel with a lower velocity than P- or S- waves, but faster than Rayleigh waves.

What is the movement of Love waves?

Love Waves—surface waves

that move parallel to the Earth’s surface and perpendicular to the direction of wave propagation

. Particle motion consists of alternating transverse motions. Particle motion is horizontal and perpendicular to the direction of propagation (transverse).

What is the characteristic of love wave?

Love waves are

transverse and restricted to horizontal movement

– they are recorded only on seismometers that measure the horizontal ground motion. Another important characteristic of Love waves is that the amplitude of ground vibration caused by a Love wave decreases with depth – they’re surface waves.

Who discovered Love waves?

What are P and S 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. … Both P and S waves

travel outward from an earthquake focus inside the earth

.

Are Love or Rayleigh waves faster?

Of the two surface waves,

Love waves move faster

. Rayleigh waves cause the ground to shake in an elliptical pattern. This motion is similar to that observed in ocean waves. Of all the seismic waves, Rayleigh waves spread out the most, giving them a long duration on seismograph recordings.

Which set of waves are the P waves?

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 is the other name of L waves?

noun Geology. an earthquake wave that travels around the earth’s surface and is usually the third conspicuous wave to reach a seismograph. Also called

long wave

.

How fast do love waves travel?

Love waves race around the Earth at

almost 10,000 miles per hour

. Their relatives, the Rayleigh waves, lag behind slightly, but still speed at about 7800 miles an hour. It seems that only the International Space Station is faster.

How do primary waves move?

Primary (compressional) waves

They travel through the Earth’s interior and can pass through both solid and molten rock. They

shake the ground back and forth – like

a Slinky – in their travel direction, but do little damage as they only move buildings up and down.

How do Rayleigh waves move?

Rayleigh waves travel along the free surface of an elastic solid such as the Earth. Their motion is a

combination of longitudinal compression and dilation

that results in an elliptical motion…

How fast are P waves?

In the Earth, P waves travel at speeds from

about 6 km (3.7 miles) per second in surface rock

to about 10.4 km (6.5 miles) per second near the Earth’s core some 2,900 km (1,800 miles) below the surface. As the waves enter the core, the velocity drops to about 8 km (5 miles) per second.

What are characteristics of wave?

• Crest = Highest point of the wave.
• Trough = Lowest point of the wave.
• Wavelength = Distance from one crest/trough to the next (m)
• Wave Height = Height from trough to crest (m)
• Wave steepness = ratio of wave height to wavelength.

What does the P stand for in P wave?

Compressional waves are also called P-Waves, (P stands for

“primary”

) because they are always the first to arrive.
