Seismic intensity scales categorize the intensity or severity of ground shaking (quaking) at a given location, such as resulting from an earthquake. They are distinguished from seismic magnitude scales, which measure the magnitude or overall strength of an earthquake, which may, or perhaps may not, cause perceptible shaking. In the United States, the Modified Mercalli (MM) Intensity Scale is used to determine the magnitude of earthquakes. The scale classifies the intensity and the observed structural damages of...Earthquake magnitudes are determined by measuring the amplitudes of seismic waves. The amplitude is the height of the wave relative to the baseline (Figure 9.13). Wave amplitude depends on the amount of energy carried by the wave. The amplitudes of seismic waves reflect the amount of energy released by earthquakes.In memory of Bishop Lakshman Wickremesinghe who died on October 23, 1983 .
