What are Seismic Waves??
A vibration that moves through the Earth.
A pressure wave where the material vibrates back and forth in the samedirection as the wave movement.Can pass through rock. Can pass through a liquid S-waves
A sideways wave in which the disturbance vibrates material side to side,perpendicular to the direction to the wave movement. Can pass through rock. Can not pass through a liquid.
Factors affecting seismic waves
distance: farther = more reduction
density: higher = faster
temperature: colder = faster
liquid vs solid
solid = faster; p-waves and s-waves
liquid = slower p waves; no s-waves
angle of incidence - controls how much isreflected and how much is absorbed.
Generally, known as Earthquake but in real it is the sudden release of the energy from earth's crust.
Type or we can say that the how strong the EQ it is predict by intensity as well as magnitude.
Magnitude doesn't effect like intensity.
Intensity depends upon the damage after the unwanted event occurs. There are lot more things taken into account for study the situation before, during and after the disastrous event.
