What are the different types of seismic waves and what are their characteristics?
Types of Seismic Waves The two main types of waves are body waves and surface waves. Body waves can travel through the Earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes send out seismic energy as both body and surface waves.
What are the characteristics of primary waves?
P waves, or Primary waves, are the first waves to arrive at a seismograph. P waves are the fastest seismic waves and can move through solid, liquid, or gas. They leave behind a trail of compressions and rarefactions on the medium they move through. P waves are also called pressure waves for this reason.
What are the major characteristics of P and S waves?
P waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth. For example, if an earthquake occurs on one side of Earth, seismometers around the globe can measure the resulting S and P waves.
What are the characteristics of the three types of seismic waves?
- Body waves travel through the interior of the Earth.
- Surface waves travel across the surface. Surface waves decay more slowly with distance than body waves which travel in three dimensions.
- Particle motion of surface waves is larger than that of body waves, so surface waves tend to cause more damage.
What are the different types of seismic 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. A P wave is a sound wave traveling through rock.
What is characteristics of secondary waves?
Secondary , or S waves, travel slower than P waves and are also called “shear” waves because they don’t change the volume of the material through which they propagate, they shear it.
What are the characteristic of Love waves and Rayleigh waves?
Love waves have a horizontal motion that moves the surface from side to side perpendicular to the direction the wave is traveling. 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.
What is the characteristics of Love waves and Rayleigh waves?
What is the characteristics of secondary waves?
What are P waves S waves and L waves?
The PP (one bounce) and PPP (two bounces) waves travel more slowly than the direct P because they pass through shallower, lower velocity rocks. The different S waves arrive after the P waves. The slowest (and latest to arrive on seismograms) are surface waves, such as the L wave.
What are the different kinds of seismic waves?
– Earthquakes produce three types of seismic waves: primary waves, secondary waves, and surface waves. – The fastest seismic waves are called primary waves, or P waves. – Secondary waves are the second seismic waves to arrive at any particular location after an earthquake, though they start at the same time as primary waves.

What are some facts about seismic waves?
Seismic waves are energy waves that are generated by an earthquake or explosion and propagate within the Earth or on its surface. Earthquakes occur when there is a movement of Earth’s tectonic plates. Seismic waves are studied by seismologists using an instrument called seismograph, which records the frequency and amplitude of the waves to
