7.0 on the Moment Magnitude Scale.
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.

The magnitude of an earthquake is a number used to quantify how much energy was released during the earthquake. The earthquake in Japan that occurred on Friday, March 10, 2011, had a moment magnitude of 8.9.
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 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.

A magnitude 6 earthquake has 10 ten times the energy of a magnitude 5 earthquake.
An earthquake's magnitude is a measure of how strong it is
The magnitude of an earthquake is caluated to measure the amount of energy released during the earthquake.
7.2 magnitude
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.
The Earthquake of February 27,2010 had a magnitude of 8.8
The magnitude of Haiti's recent earthquake was 7.0
Because the "magnitude scale is not linear, it is logarithmic (its numbers are an order of magnitude apart) this mean that the a magnitude 6 earthquake is TEN TIMES more powerful than a magnitude 5 earthquake and a HUNDRED TIMES more powerful than a magnitude 4 earthquake.

A magnitude 9 earthquake is 10,000x stronger than a magnitude 5.
The maximum ground motion of a magnitude 5 earthquake is 100 times larger than a magnitude 3 earthquake.
