What is the propagation of earthquake waves?

Seismic wave propagation is a ground motion phenomenon that relates to the passage of body waves, including compression waves and shear waves, radially from the source of earthquake energy release (hypocenter) into the surrounding rock and soil medium.

What are the 4 types of earthquake waves?

Love Waves—surface waves that move parallel to the Earth’s surface and perpendicular to the direction of wave propagation..

  • P-wave Motion. P-wave:the primary body wave; the first seismic wave detected by seismographs; able to move through both liquid and solid rock.
  • S-wave Motion.
  • Rayleigh-wave Motion.
  • Love-wave Motion.

What are the 3 types of earthquake waves?

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.

What are P S R and L waves?

Seismic Waves: The main seismic wave types are Compressional (P), Shear (S), Rayleigh (R) and Love (L) waves. P and S waves are often called body waves because they propagate outward in all directions from a source (such as an earthquake) and travel through the interior of the Earth.

What is earthquake wave 11?

Seismic waves are like those ripples which can travel through the inside of the earth, as well as on the surface. P waves, S waves, and Surface waves. Based on the medium they travel in, earthquake waves can be classified under two categories: Body waves. Surface waves.

What do you think is the source of earthquake waves and the medium of propagation?

Seismic waves are usually generated by movements of the Earth’s tectonic plates but may also be caused by explosions, volcanoes and landslides. Seismologists use seismographs to record the amount of time it takes seismic waves to travel through different layers of the Earth.

Who was the love wave named after?

mathematician A. E. H. Love
Love Waves One kind of surface wave is called a Love wave, named after British mathematician A. E. H. Love, who worked out the mathematical model for this wave type in 1911. Love waves produce entirely horizontal motion.

What is P wave 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 is an L wave in an earthquake?

Pronunciation: [key] an earthquake wave that travels around the earth’s surface and is usually the third conspicuous wave to reach a seismograph.

What is R wave in earthquake?

Rayleigh (R) waves are very similar to water waves – a piece of the Earth’s surface moves in a vertical, elliptical path parallel to the direction of wave movement when an R-wave passes through the crust..

What are P waves?

What is L wave earthquake?

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.
