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.
Technically there are 4 types; P-wave(primary), S-wave(secondary), Love wave. and Rayleigh wave, the love and rayleigh are surface waves and they are difficult to differentiate on seismograph and so are counted as one. Although all three are equally damaging, by damage it means intensity of the earthquake. The intensity depends upon the infrastructure, for instance, mason structures are stable and strong it requires are really strong shock to be damaged. When an earthquake takes place, four types of seismic waves travel from the epicenter. 1  The fastest traveling wave is the P-waves; Primary waves or P-waves AKA compressional waves that are longitudinal in nature. 2  Next is the S-waves, Secondary waves or S-waves AKA shear waves that are transverse in nature.
