Magnitude. A familiar analogy to help understand earthquake size metrics is to think about a light bulb. One measure of the strength of a light bulb is how much energy it uses. A 100-watt bulb is brighter than a 50-watt bulb, but not nearly as bright as a 250-watt bulb. The wattage of a bulb tells you about the strength of the light source.An earthquake refers to the shaking of the earth’s surface caused by a sudden release of energy within the earth’s crust. This release of energy generates seismic waves, commonly known as S waves. The intensity and characteristics of an earthquake are determined by the seismic activities occurring in a specific region. An earthquake’s strength can be measured in a variety of ways; the two most common methods are intensity and magnitude. Earthquake intensity is a measurement of the surface damage resulting from an earthquake. It is most commonly measured with the Mercalli scale as seen in Figure 10.Geology. The intensity is a number (written as a Roman numeral) describing the severity of an earthquake in terms of its effects on the earth’s surface and on humans and their structures. Several scales exist, but the ones most commonly used in the United States are the Modified Mercalli scale and the Rossi-Forel scale.Magnitude.

The simulation is based on a detailed geologic model of the central U.S. and is intended to show the general character of the ...The intensity of an earthquake is the strength of the shaking caused by the earthquake. Intensity is measured on the Modified Mercalli Scale. This is a scale that is based on effects observed from the earthquake and to what degree those effects are felt. It ranges on a scale from 1 to 12, one being the lowest effects and 12 being total loss.

The intensity at a specific location is a measure that depends on the effects of the earthquake on people or buildings. Intensity is expressed in Roman numerals or whole numbers (e.g., VI or 6). Although there is only one magnitude for a specific earthquake, there may be many values of intensity (damage) for that earthquake at different sites.
