Types of seismic waves
P and S waves; body waves and surface waves
Reading seismograms
Identify different waves by their arrival times, amplitudes and periods.


What is a Wave ?
A wave is a disturbance or variation that transfers energy progressively from point to point in a medium.
Examples:
Sound wave: variation of pressure in the air
Radio wave: variation of EM intensity
Water wave: variation of water surface
Seismic wave: variation of elastic deformation in rocks
Note that the medium doesn’t travel along with the wave.
Waves like the EM wave do not even need a medium to propagate.

Wave Speed
It is the speed that the wave travels.
The wave speed is a material property. No matter how big the wave is, it travels at the same speed.
Sound wave speed in dry air v = 331 + 0.6 T (m/s) where T is temperature in Celsius
Elastic wave speeds in rocks are 1 ~ 10 km/s, depends mainly upon temperature, pressure, and composition.
