  1. Jan 17, 1994 · The Modified Mercalli Intensity Scale. 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 furniture, damage to chimneys, and finally - total destruction. Although numerous intensity scales have been developed over the ...

  2. Aug 11, 2020 · The intensity scale is a qualitative scale because it is not based on specific measurements, even though it has numbers. It is important to realize that intensity refers to the damage caused at a particular place by an earthquake. An earthquake will have different intensities in different places.

  3. Intensity is a measure of the strength of shaking experienced in an earthquake. The Modified Mercalli Scale represents the local effect or damage caused by an earthquake; the "intensity" reported at different points generally decreases away from the earthquake epicenter. The intensity range, from I - XII, is expressed in Roman numerals.

  4. The first intensity scale of modern times was developed by De Rossi of Italy and Forel of Switzerland in 1880s. This scale, which is still sometimes used in describing damage effect of an earthquake, has values I to X. The 1906 San Francisco earthquake was rated with the Rossi-Forel intensity scale. For description of this scale readers are ...

  5. 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. At high intensities (above MMI 6), earthquake shaking damages buildings. The severity of the

  6. Jul 08, 2017 · Modified Mercalli Intensity Scale (Earthquake Damage Reporting) By John Jacob Schmidt, AmRRON. In the immediate aftermath of an earthquake, search and recovery efforts will be on the way and conventional communications and mobility are usually disrupted or destroyed.

  7. The general location of the earthquake and regions likely to have experienced the most severe damage are also readily identifiable on the resulting intensity map. Here's an example from the 1966 Parkfield earthquake (Parkfield is located in central California).
