Richter scales are useful to measure only small, shallow earthquakes recorded within a certain distance from the epicenter. A moment magnitude scale is more precise than a Ric…hter scale. It also gives a measure of the energy released during an earthquake. (MORE)

The Richter magnitude scale allows us to compare estimates of the energy released by an earthquake. An earthquake sends out compression waves from its epicentre. The more inte…nse the earthquake, the bigger the amplitude of these waves. The Richter scale measures the amplitude of the waves, but not in a linear way. Instead, it measures the logarithm of the amplitude. This means that an earthquake of magnitude 7 has waves that are 10 times smaller than an earthquake of magnitude 8 - which is the largest quake that can be measured in this way. A magnitude 0 quake is so tiny that you could never possibly feel it. The amplitude of the wave is quite closely related to the energy released, so that a magnitude 8 earthquake is 32 times as powerful as a magnitude 7, which is in turn 32 times as powerful as a 6, and so on.

The data show what kinds of seismic waves the earthquake produced and how strong they were. The data also help geologists infer how much movement occurred along the fault …and the strength of the rocks that broke when the fault slipped. Geologists use all this information to rate the quake on the moment magnitude scale. (MORE)

the moment magnitude scale is used to measure earthquake magnitude-taking into account the size of the fault rupture, the rocks stiffness,and the amount of the movement of the… fault- using values that can be estimated from the size of several types of seismic waves. while a richter scale is a numerical scale used to measure the magnitude of an earthquake, using values based on the size of the earthquakes largest seismic waves.

Earthquakes with a magnitude greater than or equal to 6 are termed strong earthquakes. 7 or larger are termed major earthquakes. Earthquakes greater than or equal to 8 are ter…med great earthquakes. The term "large" is not actually used.However based on the above it could be argued that any earthquake with a magnitude greater than 6 is a large earthquake. (MORE)

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4
