Eventually, shaking intensity scales were developed to standardize the measurements and ease comparison of different earthquakes. Shaking intensity varied from barely perceptible to completely destructive. Since 1933, in the United States we have used what's called the Modified-Mercalli Intensity scale, a twelve-stage scale, numbered from I to XII.The Mercalli intensity scale (or more precisely the Modified Mercalli intensity scale) is a scale to measure the intensity of earthquakes. Unlike with the Richter scale , the Mercalli scale does not take into account energy of an earthquake directly.Mercalli Intensity Scale. Earthquakes are described in terms of what nearby residents felt and the damage that was done to nearby structures. Richter magnitude scale.
