An earthquake with a magnitude of 5.0 has a shaking amplitude 10 times that of an earthquake with a 4.0 magnitude.
Because the Richter scale of measuring the magnitude of energy is a logarithmic scale, each position is 10x as energetic as the previous position. As a result, a magnitude 5 earthquake is ten times as energetic as a magnitude 4 earthquake and one-hundred times as energetic as a magnitude 3 earthquake.
A 5.0 magnitude earthquake releases about 32 times as much energy as a 4.0 event. The energy released is equal to the 3/2 power of the multiple of shaking amplitude. (The square root of the third power of the change in amplitude. Here the change is 1.0 on the Richter scale, so the amplitude multiple is 10 and the energy is sqrt(103) which is sqrt(1000) or 31.6 times the energy.)
31.6 times more energy is released from a magnitude 5.0 earthquake than a magnitude 4.0 earthquake.
An earthquake with a magnitude of 5.0 has a shaking amplitude 10 times that of an earthquake with a 4.0 magnitude.
The magnitude 6.5 earthquake releases 31.6 times more energy than a magnitude 5.5 earthquake.

A 3.0 earthquake releases 1,000 times more energy than a 1.0 earthquake.
The Richter magniude scale is logorithmic. As such the size (amplitude) of the largest seismic waves produced by a magnitude 7 earthquake are 102 (or 100) times larger than those produced by a magnitude 5 earthquake. However the amount of energy released by a magnitude7 earthquake is 1000 times greater (102)^3/2 than a magnitude 5 earthquake and so it is likely to be much more destructive.
The amplitude (height) of the seismic waves in a magnitude 8 earthquake will be ten times larger than in a magnitude 7 quake. This equates to approximately 31 times more energy.
Tectonic plate size does affect earthquake magnitude. Earthquakes happen when one plate slides above/below another plate, to do this it takes massive amounts of convection energy from the mantle to move the plate above. The larger the mass of the plate, the more energy is needed to move it which means that large plates have a lot of stored up energy in them before the quake in question. When the energy is released the plate boundary snaps releasing all the built up energy. As there was so much energy stored in the plate the more is released, causing a larger, more devastating earthquake.
0.3 magnitude
30 times more energy released. 10 times more ground motion*
The measure of energy released by an earthquake depends on its magnitude. If its a high magnitude earthquake, there is a lot of energy. If there is a low magnitude, then there is little energy.
Seismic energy increases by a factor of about 31.6 for each increase of magnitude, so a magnitude 3 earthquake has 31.6 times more energy released than a magnitude 2 earthquake.
The earthquake magnitude is a measure of the energy released during an earthquake. The scale is logarithmic, such that a magnitude of 6.0 releases about 32 times more energy than a magnitude 5.0 earthquake, and in turn more than 900 times more energy than a magnitude 4.0 earthquake.
Roughly 32 times more energy is released in a Magnitude 6 earthquake than in a Mag.5 quake.
30 times
Magnitude scales are measurements of the amount of energy released by an earthquake. Perhaps the most famous is the Richter magnitude scale although this has since been replaced by the moment magnitude scale. Please see the related questions for more information.
A magnitude 6 earthquake emits roughly 31 times more energy than a magnitude 5 earthquake. The magnitude 6 quake will also have a maximum seismic wave amplitude of ten times the magnitude 5 earthquake.
Because magnitude is a measurement of the amount of energy released in an earthquake and this value will remain constant once the earthquake has finished. However the estimates seismologists make of this value may change as they gain more information about the earthquake...
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.
about a 1000
It means that a certain amount of shaking occurs near the earthquake; or equivalently, that a certain amount of energy is released. For more details on how this magnitude is defined, check the Wikipedia article on "Richter magnitude scale".
