Definition : The Richter scale is a measurement tool that defines the moment magnitude of an earthquake (also called earthquake), not its intensity. This measure was developed by Charles Francis Richter (1900 – 1985), an American seismologist in 1935.
The essential feature of this scale is that it is open. This means that it has no upper limit.
From a practical and historical point of view, the Richter scale is in fact limited to 9, which is the maximum upper limit ever observed. The strongest measured earthquake has a magnitude of 9.5 on the Richter scale measured in Chile during an earthquake in 1960.
There is another scale that measures the intensity (measure of damage caused by the earthquake) and magnitude of earthquakes. This is the Mercali scale.

Microearthquake impossible to feel but recordable by seismometers.Microearthquake impossible to feel but recordable by seismometers..So it’s not possible to feel it…
Strong earthquake capable of causing major destruction over a large distance (180 km) around the epicentre..<8.0 to 8.9.
| Less than 1.9 | Micro-earthquake impossible to feel. |
| From 2.0 to 2.9 | Micro-earthquake impossible to feel but recordable by seismometers. |
| From 3.0 to 3.9 | Does not cause damage but is beginning to be felt slightly. |
| From 4.0 à 4.9 | An earthquake that can move objects but does not usually cause damage. |
| From 5.0 to 5.9 | Earthquake capable of causing significant damage to old buildings or buildings with construction defects. Little damage to modern buildings. |
| From 6.0 to 6.9 | Strong earthquake capable of causing major destruction over a large distance (180 km) around the epicentre. |
| From 7.0 to 7.9 | Earthquake capable of major to moderate destruction over a very wide area depending on distance. |
| From 8.0 to 8.9 | Earthquake capable of major destruction over a very large area of several hundred kilometres. |
| Above 9 | Earthquake capable of destroying everything over a very large area. |
