What is intensity of an earthquake

A magnitude 9.0 earthquake, which rarely occurs, releases over a million times as much energy as a magnitude 5.0 earthquake. Ranking Earthquake Intensity. Earthquake intensity is very different from earthquake magnitude. Earthquake intensity is a ranking based on the observed effects of an earthquake in each particular place. .

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. An earthquake's magnitude is expressed in whole numbers and decimals (e.g., 6.8). The intensity at a specific location is a measure that depends on the effects of the earthquake on people or buildings. Intensity is …A magnitude 9.0 earthquake, which rarely occurs, releases over a million times as much energy as a magnitude 5.0 earthquake. Ranking Earthquake Intensity.
