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.
By definitiona an aftershock is always smaller than the larger earthquake that preceeded it. If an earthquake then occurs that is of larger magnitude and related to the prior seismic activity it is redesignated as the mainshock and all pre-recording quakes are re-designated as foreshocks.
The Richter or local magnitude scale of the Haitian earthquake has been reported as 7.2. and the Moment magnitude as 7.0 (according to the U.S. Geological Survey, National Earthquake Information Center).Please see the related questions for further information about the Haitian earthquake and it's magnitude and severity.7.0 magnitutes
The Richter or local magnitude scale of the Haitian earthquake has been reported as 7.2. However the Richter Magnitude Scale is no longer the formal scale used for reporting earthquake magnitude having been replaced by the Moment Magnitude Scale.As such, the official strength of the January 12, 2010, quake on the Moment Magnitude Scale was 7.0, as reported by the U.S. Geological Survey, National Earthquake Information Center.Please see the related questions for further information about the Haitian earthquake and it's magnitude and severity.
The earthquake had a Moment magnitude of 7.0 and a Mercalli intensity of Extreme (Level X). Please see the related questions for more information.
The larger the magnitude of the earthquake, the larger the energy to be released by the earthquake.

The moment magnitude uses seismographs plus what physically occurs during an earthquake.

The Richter scale is related to the effects of an earthquake rather than the energy released.
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 Perhaps the most famous is the Richter magnitude scale although this has since been replaced by the moment magnitude scale.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.
They both based on the amount of energy that is released during earthquake
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.
Broadly speaking, the amount of damage an earthquake causes will increase as it's magnitude increases. For more information on this topic, please see the related questions.
No, the Haitian earthquake which occurred on the 12th of January, 2010 had a magnitude of 7.0. Please see the related question for more information.
The highest magnitude earthquake ever recorded was the 9.5 magnitude earthquake that struck Chile on the 22nd of May, 1960. Please see the related link.
