Most of the energy of an earthquake is transported through the Earth's crust in the form of seismic waves. These waves can be either body waves (P-waves and S-waves) that travel through the interior of the Earth, or surface waves that travel along the Earth's surface. The energy is gradually attenuated and dispersed as the waves propagate through the crust.
Sound waves are generated by vibrations in air or a medium and travel in all directions from the source, whereas earthquake waves are generated by the sudden release of energy in the Earth's crust and travel through the Earth. Sound waves are longitudinal waves that can travel through gases, liquids, and solids, while earthquake waves consist of P-waves (compressional waves) and S-waves (shear waves) that travel at different speeds and have different effects on the Earth's surface.
The fastest waves shaking the ground like an accordeon (contraction and expansion) are the P waves. They have a global velocity of 5.5km/s in the crust while S waves moves at velocities around 3.2 km/s in the crust. Then you have surface waves (rayleigh and Love) which propagates only in the crust at velocities smaller than the S waves velocity.
The type of earthquake wave that moves only through the crust and mantle is called the S-wave (secondary wave). S-waves are slower than P-waves, cannot propagate through liquids like the outer core, and cause side-to-side shaking motion.
P-waves typically arrive first during an earthquake, followed by S-waves, and then L-waves. P-waves are compressional waves that travel fastest through the earth's interior, followed by S-waves which are shear waves. L-waves are surface waves that travel along the earth's crust.
when the crust breacks apart it reveles objects beneth earths iner crust.
They show that the outer core of the Earth is liquid while the inner core is solid.
When a shift occurs in the Earth's crust, the energy can radiate as seismic waves. These waves travel through the Earth's interior and can be detected and measured by seismographs. Depending on the type of fault movement, the seismic waves produced can be either compressional (P-waves) or shear (S-waves).
Seismic waves are the earths crust vibrating. there are two types of waves P-waves and S-waves (Primary and Secondary) Primary waves travel faster than s waves and can travel through solid and liquid, S-waves can only travel through solids
S-waves are not transmitted through the outer core.
an earthquake forms deep in side the earths crust, where plates, that hold continents, are. they move, sideways, forward, backward and slide over other plates. if two plates meet sliding or bumping each other, it cause waves over the earth, which we call earth quakes.These waves, animals can sense. there are three diffrent waves that come from an earthquake.P waves S waves and surface waves. the waves come over the earth, and some are silent at first,which the animals hear. the big ones, shake the earths crust, causing the crust to shake which we are on and buildings. and since the earth below us is moving, the building shake and fall, causing damage.
yes. Earths crust is 20 miles thick and the moon"s crust is 40 miles thick.
s waves
When part of the Earth's crust breaks, seismic waves pass through the Earth. These waves include primary (P) waves, secondary (S) waves, and surface waves. P waves are the fastest and can travel through both solids and liquids, while S waves are slower and can only travel through solids. Surface waves cause the most damage during an earthquake.
L waves are formed when P&S waves reach the surface.

Body waves travel through the inside of earth's surface.Surface waves travel through the top part of earth's crust
