Following the energy release of the rupture in the epicenter, the surrounding soil and rock goes into a cycle of expansion and contraction (waves). These move as if a rock was dropped in a pond with the main difference being the soil strata is not

as homogeneous as the water, thus amplitudes are increased or decreased depending on the type of soil wave is passing from.

What waves go through the earth's atmosphere?

Elastic waves, particularly sound waves and seismic waves, can travel through the Earth's atmosphere. Sound waves propagate through the air, while seismic waves are generated by earthquakes and travel through the Earth's crust and mantle.

What is the first type of wave in an earthquake called?

The first type of wave in an earthquake is called the primary wave or P-wave. P-waves are the fastest seismic waves that travel through the Earth's interior, causing the ground to move back and forth in the direction the wave is traveling.


The waves of energy that an earthquake produces?

The waves of energy produced by an earthquake are called seismic waves. These waves travel outward from the earthquake's epicenter in all directions, causing the ground to shake. There are two main types of seismic waves: body waves, which travel through the Earth's interior, and surface waves, which travel along the Earth's surface.


Which way do secondary waves go in?

Secondary waves, also known as shear waves, move by causing particles to move perpendicular to the direction of wave travel. This results in a side-to-side motion that causes rocks to shear horizontally. Secondary waves are the second-fastest seismic waves and are responsible for causing the ground to shake during an earthquake.


What ares seismic waves?

Seismic waves are vibrations that travel through the Earth carrying the energy released during earthquakes. == Seismic waves are waves that are a result of earthquake activity in the earth. There are body and surface waves. Body waves happen inside the earth and are called P (longitudinal) and S (transverse) waves. Surface waves happen on the Earth's surface and are called Rayleigh and Love waves. P-waves (primary waves) go first, compress and expand the earth, and are faster. S-waves (secondary waves) go second, move the ground up and down or side to side, and are not as fast as P waves.

Which type of seismic waves can make the ground go side-to-side?

S-waves go up and down while P--waves go back and fourth.


How does the structure of the earth's interior affect seismic waves?

Earthquakes are made up of 4 different seismic waves, P, S, L and R. L and R are surface waves, and have virtually nothing to do with the interior. However, P and S are body waves and do. P waves are compressional waves, that is they push and pull against rock in the same direction as the waves move. They are the fastest. S waves vibrate material up and down. Both travel faster in more dense material, and P waves travel slower in liquid while S waves are unable to move through liquid at all. As the Earth's outer core is liquid, and inner core is very dense, this affects the waves as they travel through the Earth. It speeds them up and slows them down according to the density. Because S can't go through the outer core, there is a "shadow zone" at a certain area on the Earth where there are no S waves at all. P waves also have a smaller shadow zone, where the waves are diflected and bent within the outer core.


What is the arrival of p waves and s waves?

S waves travel only through solids, they are known as shear waves and their motion is perpendicular to the direction of travel.If the direction of motion is to the right, the wave would move up and down.P waves an move through both solids and liquids, their motion is parallel to the direction of travel.If the motion is to the right the wave will compress and decompress towards the right.


How does earths solid inner core affect seismic waves?

They go faster through the inner core than the liquid outer core.


What happens to seismic waves when they pass through the liquid outer core?

There are two types of waves. There are S waves (sheer waves) and P waves (compressional waves). The S waves won't travel through the outer core because it's a liquid, but the P waves will go through it and continue going through the inner core as well.
