It measures the damage from earthquakes and the observed …

The most common intensity scale used in Australia is the 12-point Modified Mercalli scale. On this scale, intensities up to 5 are felt but cause no damage, while intensities from 6 to 12 cause increasing amounts of damage. A Modified Mercalli Intensity of six is abbreviated as MMI 6. The Mercalli Scale: A Measure of Intensity Earthquake intensity is a measure of the effects of an earthquake at a particular place. It is determined from observations of an earthquake’s effects on people, structures, and the Earth’s surface.

While the perhaps more familiar parameter of magnitude is a measure of the energy that an earthquake releases, the " intensity " of a quake is a measure of the ground shaking severity at a given point. It is thus ...

The magnitude of the earthquake is measured on the Richter scale. Charles F. Richter developed the Richter Scale in 1935. The intensity scale is named after Mercalli, an Italian seismologist. The intensity scale takes into account the visible damage caused by the event. The range of intensity scale is from 1-12.

The Modified Mercalli Scale of Earthquake Intensity In seismology a scale of seismic intensity is a way of measuring or rating the effects of an earthquake at different sites.

By using a common rating scale, engineers can compare earthquake activity measured from everywhere on Earth. Analyzing the amount of energy released by an earthquake helps with future prediction of the size and …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 earthquake.

It was originally introduced by the Italian seismologist Giuseppe Mercalli in 1902, and was modified and updated for "modern" building practices in 1931. It has twelve levels describing the strength of shaking. At a Modified Mercalli Intensity of I: Hanging objects may swing back and forth; People do not feel any earth movement; Most people indoors feel movement; Plaster in walls might …A modified Mercalli intensity scale is used to quantify the earthquake's effects. That's why you can't directly convert the Richter or Magnitude scale to the Mercalli scale — although the released energy, local geology, terrain, depth of an earthquake and distance from the epicenter are all still the same. Thus, the Mercalli scale describes ...Making Sense of the Modified Mercalli Intensity Scale (MMI) –A Measure of Shaking The Modified Mercalli Intensity (MMI) estimates the shaking intensity from an earthquake at a specific location by considering its effects on people, objects, and buildings.
