Richter Scale is calculated based on the seismic waves generated by an earthquake, while the effects of an earthquake on people, structures, and the environment determine Mercalli Scale.Magnitude (a.k.a. the Richter Magnitude scale) measures the amount of energy released at the earthquake’s epicenter. The scale can go up to as high as 9.5 (this was the largest ever recorded in ...There are two commonly-used ways of rating earthquakes: 1) the Richter scale and 2) the Mercalli Scale. The Mercalli Scale was used earlier than the Richter Scale. It describes the damage left by an earthquake, not the actual force of the earthquake. The Mercalli Scale uses human observation to assess damage from an earthquake, while a Richter ...Intensity Scale Mercalli Modified: Magnitude (Richter Scale) Max. Terrain Acceleration (g) I: Not Felt: 2.3: 0.002: II: Felt only by some people in resting position, especially in high floors. Suspended objects oscillate a little. 2.3 - 2.9: 0.002 - 0.003: III: Felt indoors. Many people do not recognize it as an earthquake. Standing cars sway.So, for example, a magnitude 2 earthquake is 31 times more powerful than a magnitude 1 earthquake. The moment magnitude scale is often referred to by the name of its predecessor, the Richter Scale. Measurements on the Modified Mercalli Intensity (MMI) scale range from I to XII and are based solely on damage assessment and eyewitness accounts.The scale is labeled from 1 - 10, with 0 serving as the baseline against which the energy is measured, the truth is that the scale has no lower limit. Therefore, a seismograph is what scientists have been using to quantify the earthquake, as well as the Richter scale is indeed a technique to put the information or findings into context.The proposed intensity scale is called the modified Mercalli (MM), scale (Wood and Neumann, 1931). It has been repeatedly revised: e.g., variants of this scale proposed by C. Richter (1958), R. Brazee (1978), and K. Stover and J. Coffman (1993). This scale is still widely used in many countries to determine earthquake strength.Learn how the Richter scale measures magnitude and the Mercalli scale measures intensity of ... scale of 12 grades is similar to the abridged version of the Mercalli.
