The population growth rate is much lower than the state average rate of 6.90% and is much lower than the national average rate of 11.61%.
Earthquakes generate three types of seismic waves: P (primary) waves, S (secondary) waves and surface waves, which arrive at seismic recording stations one after another. Both P and S waves penetrate the interior of the Earth while surface waves do not. Due to this, P and S waves are known as body waves.
Light and sound both travel in this way. Energy released during an earthquake travels in the form of waves around the Earth. Two types of seismic wave exist, P-and S-waves. They are different in the way that they travel through the Earth.P-waves (P stands for primary) arrive at the detector first. They are longitudinal waves which mean the vibrations are along the same direction as the direction of travel.wo types of seismic wave exist, P-and S-waves.
