The lower numbers of the intensity ...The Richter Magnitude scale is one such scale that you have likely heard of. Figure 6.2. 1: Seismogram. One issue with measuring earthquakes is that as the waves propagate, the energy is spread out over more area. Figure 6.2. 2: Distance from Source. As E A r e a ↓, the amplitude decreases with distance. Intensity measurements near the source of an earthquake are generally higher than those at a distance. Determining intensity can be difficult in sparsely populated areas with few buildings because intensity is calculated largely based on the effects that tremors have on human-made structures.

Magnitude and Intensity of Earthquakes: Magnitude and intensity are two ways of measuring the strength of an earthquake.
