Difficult to stand; furniture broken; damage negligible in building of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built or badly designed structures; some chimneys broken. The modified Mercalli intensity scale (MM or MMI), developed from Giuseppe Mercalli's Mercalli intensity scale of 1902, is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake. The MM scale grades the impact of an earthquake on people living on the earth's surface, and so can be more useful as an indicator of the earthquake's significance to the community. I.

Giuseppe Mercalli (1850-1914) originally developed the scale with ten levels. For example, on May 19, 2011, an earthquake of magnitude 0.7 in Central California, United States 4Â km deep was classified as of intensity III by the United States Geological Survey (USGS) over 100 miles (160Â km) away from the epicenter (and II intensity almost 300 miles (480Â km) from the epicenter), while a 4.5 magnitude quake in Salta, Argentina 164Â km deep was of intensity I.

The effect of an earthquake on the Earth's surface is called the intensity. It is known today as the Modified Mercalli Intensity Scale.The Richter Magnitude Scale was developed in 1935 by Charles Richter. The Mercalli intensity scale (or more precisely the Modified Mercalli intensity scale) is a scale to measure the intensity of earthquakes. 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. Chaque lettre qui apparaît descend ; il faut placer les lettres de telle manière que des mots se forment (gauche, droit, haut et bas) et que de la place soit libérée. From a scientific standpoint, the magnitude scale is based on seismic records while the Mercalli is based on observable data which can be subjective. In 1902 the ten-degree Mercalli scale was expanded to twelve degrees by Italian physicist Adolfo Cancani.
