The Richter magnitude scale is a base-10 logarithmic scale of the shaking amplitude. This means that a difference of 1 in the scale is equivalent to a 10-fold increase in amplitude. So the difference in amplitude between a mag 8 and a mag 4 earthquake is 104.

How much less energy does a magnitude 4 earthquake have than a magnitude 7?
Each increase by one magnitude corresponds to a release of energy 31.6 times that released by the lesser earthquake.Since 7 is 3 magnitudes higher than 4, the magnitude 4 earthquake has roughly 1/31554th the energy of the magnitude 7.Each increase by one magnitude corresponds to a release of shaking amplitude 10 times that released by the lesser earthquake.Since 7 is 3 magnitudes higher than 4, the magnitude 4 earthquake has 1/1000th the shaking amplitude of the magnitude 7.The amount of energy changes much more rapidly with magnitude than the amount of shaking amplitude. This is a commonly made error.
How much greater is a magnitude 7.0 earthquake than in comparison to a 6.0 earthquake?
My understanding of the magnitudes of earthquakes is that each decimal point is equal to a magnitude of strength 10x more than the previous number. Example would be that a 4.2 earthquake is 10x stronger than a 4.1 earthquake. Therefore, a magnitude 8.5 EQ is 100x stronger than a 7.5 EQ.
How much more energy does a Richter magnitude 6 release compared to a magnitude 3?
Every change of 1 on the Richter scale increases the amplitude of the measured seismic waves of the earthquake by a factor of 10 and the energy released scales with the shaking amplitude based on the following: Change in energy released = (10^Md)^(3/2) Where Md = difference in magnitude between two earthquakes (in the example above this is 3.0) Therefore a magnitude 6.0 earthquake releases (10^3.0)^(3/2) = 31,622 times more nergy than a magnitude 3.0 earthquake and has seismic waves with 1000 times larger amplitude.
A magnitude 6 earthquake is how many times greater than a magnitude 5 earthquake?
1000 times as much
What is the magnitude of an earthquake and how do you measure it?
The magnitude of an earthquake is a method of describing how much energy is released when the earthquake occurs. It can be estimated based on the amplitude of the seismic waves released or based on the length of the fault rupture zone, the size of the slip and the elastic modulus of the surrounding rocks. For more information see the related questions.

How much does the amplitude of the wave increase between an earthquake that measures 4.2 on the Richter scale and an earthquake that measures 6.2 on the Richter scale?
The energy released by an earthquake increases by 10x for every 1.0 increase in magnitude on the Richter scale. A 6.2 quake is 2.0 higher than a 4.2 quake. The increase in energy output would be calculated as such: 10x10=100. A 6.2 magnitude earthquake is 100 times more powerful than a 4.2 magnitude earthquake.
