The effect of an earthquake on the Earth's surface is called the intensity. The intensity scale consists of a series of certain key responses such as people awakening, movement of …

The Modified Mercalli intensity scale (MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an …

Intensity describes how strong the shaking is at a given location. In the United States and many other locations, intensity values are described with Roman numerals from I (barely perceptible) …

Scientists developed a scale to quantify an earthquake's shaking by what was felt and by its effects on structures and the landscape. The most widely used scale is the Modified Mercalli …

The Richter scale and the moment magnitude scale are logarithmic. The amplitude of the largest wave increases ten times from one integer to the next. An increase in one integer means that …

One common way to measure earthquake intensity is through the Modified Mercalli Intensity Scale (MMI). This scale is derived from an earlier ten-degree Rossi-Forel scale, which was …

Table of earthquake intensity, witness perceptions, and damage.

Intensity scales are based on the observed effects of the shaking, such as the degree to which people or animals were alarmed, and the extent and severity of damage to different kinds of …
