An increase of 1.0 on the magnitude scale equals 32 times the energy release. Therefore an increase of 2.0 would be 32x32, which is 1024 time the energy release.
So a magnitude 7 earthquake releases 1024 times more energy than a magnitude 5.

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 Perhaps the most famous is the Richter magnitude scale although this has since been replaced by the moment magnitude scale.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.
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.
magnitude
They both based on the amount of energy that is released during earthquake
The word used to describe the amount of energy released by an earthquake is "magnitude." This is typically measured using the Richter scale or the moment magnitude scale.
This is known as the magnitude of the earthquake.
The word Magnitude is used to described the amount of energy released when an Earthquake occurs
The amount of energy released by an earthquake is measured on the moment magnitude scale, often referred to as just magnitude. This scale takes into account the seismic moment, which is a measure of the total energy released during an earthquake. The magnitude is expressed in whole numbers and decimal fractions.
It is caused by the rotation of earth.
magnitude.
The energy of seismic waves increases with magnitude. A small increase in magnitude corresponds to a large increase in energy released. The magnitude scale is logarithmic, so each whole number increase in magnitude represents a tenfold increase in amplitude and approximately 32 times more energy.
