they occur i think in the plate boundarys.
S-waves are slower than P-waves, which are the fastest seismic waves. S-waves are shear waves that move in a back-and-forth motion, causing particles to move perpendicular to the direction of wave propagation.
Secondary waves.
P-waves are longitudinal and S-waves are transverse waves.
Their velocity (P-waves travel more quickly than S-waves) and their mode of propagation (the way they move through the earth). S-waves are transverse waves which move material from side to side (particle motion is normal to direction of travel) whereas P-waves are compression or longitudinal waves where particle motion is parallel to the direction of travel. This means that P-waves can travel through solids, liquids and gasses whereas S-waves can only travel through solids.
P and S waves are body waves.
There are 3 main waves types associated with earthquakes. P(primary), S (secondary and T (tertiary). Both P and S waves are body waves and occur rather quickly. Tertiary waves are waves that are slower than P and S and are recorded in the SOFAR regions of the ocean and occur due to multiple reflections of the wave between the sea floor and sea surface.
P-waves are faster than s-waves. Both can pass through solid rock, but only p-waves can pass through gases and liquids === ===
To determine the approximate location and the time the earthquake will occur.
For P waves, the two descriptive words are Primary (or compressional) waves, while for S waves, the two words are Secondary (or shear) waves.
No, surface waves move slower than P-waves and S-waves. P-waves are the fastest seismic waves, followed by S-waves, and then surface waves. Surface waves travel along the Earth's surface and are responsible for the most damage during an earthquake.
P waves have a higher velocity than S waves. This is known because P waves (Primary waves) arrive at recording stations faster than all other waves. S waves (Secondary waves) arrive second at recording stations.
P-waves are longitudinal and S-waves are transverse waves.
