ent denitions, methods, nor a clear sense of scale to distinguish one term from another (Caldera et al. 2016a). To describe the severity level of a natural disaster, which can range from a small community re to large-scale events such as a tsunami or earthquake, we often use words such as “emergency,” “disaster,” and “catastrophe.”

Intensity scales, like the Modified Mercalli Scale and the Rossi-Forel scale, measure the amount of shaking at a particular location. An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are.

January 1, 1982. Earthquakes can be measured in terms of either the amount of energy they release (magnitude) or the degree of ground shaking they cause at a particular locality (intensity). Although magnitude and intensity are basically different measures of an earthquake, they are frequently confused by the public and new reports of earthquakes.

The Modified Mercalli Intensity value assigned to a specific site after an earthquake has a more meaningful measure of severity to the nonscientist than the magnitude because intensity refers to the effects actually experienced at that place.

An earthquake is a sudden shaking or rolling of the ground caused by movements under the earth’s surface. Some earthquakes can be mild while others may be severe causing massive devastation to structures, life and other natural resources.

The Modified Mercalli Intensity (MMI) Scale is a qualitative ranking system that describes the severity of shaking in specific locations during an earthquake. The scale is composed of increasing levels of intensity that range from imperceptible shaking to catastrophic destruction. Each ranking is assigned a Roman numeral from 1 to 10 (I-X).
