The Mercalli scale is a twelve point scale, 1 being almost undetectable and 12 being complete destruction. The scale was expanded to accommodate 12 degrees of intensity by Adolfo Cancani in 1902. It varies from place to place within the disturbed region depending on the location of the observer with respect to the earthquake epicenter.

In earthquake: Intensity scales …in North America is the Mercalli scale, as modified by Harry O. The Richter scale was developed in 1935 by Charles Richter, along with his associate, Beno Gutenberg, and today it is the commonly used scale in earthquake measurement. The scale commonly used to measure the magnitude of an earthquake is the Richter Magnitude Scale. An earthquake which registers low intensity is addressed as an I. Es wurde ursprünglich entwickelt, um ein bestimmtes Gebiet in Kalifornien mit dem Wood-Anderson-Torsionsseismographen zu untersuchen und die Größe verschiedener Erdbeben in der Region zu vergleichen. The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally - total destruction. n. A scale of earthquake intensity based on observed effects and ranging from I to XII . Ironically, it was Charles Richter who gave the scale its updated form which is used today, presently called the MMI scale, or known as the Modified Mercalli scale.

The Modified Mercalli Intensity Scale The effect of an earthquake on the Earth's surface is called the intensity. Modified Mercalli intensity VIII is roughly correlated with peak accelerations… A Richter scale is normally numbered 1-10, though there is no upper limit. The Mercalli intensity scale (or more precisely the Modified Mercalli intensity scale) is a scale to measure the intensity of earthquakes. The Modified Mercalli Intensity Scale. It's based around measuring the destructive capability of an earthquake. It was modified again by Harry O. In New Zealand, where earthquakes occur from near the surface right down to a depth of over 600 km, the Modified Mercalli intensity scale is a better indicator of an earthquake's effects on people and their environment. Intensity is based on the observed effects of ground shaking on people, buildings, and natural features.

Die Richter Magnitude Scale wurde 1935 von Charles Richter entwickelt. The scale was designed to determine the extent of damage in the aftermath of an earthquake. New Zealand scientists have modified it further to suit New Zealand conditions. Earthquake Intensity Risk Zones. …in North America is the Mercalli scale, as modified by Harry O. This map shows earthquake intensity zones in accordance with the 1956 version of the Modified Mercalli Scale (MM), … Mercalli ratings are assigned by Roman numerals.
