The "moment" magnitude of an earthquake is a measure of how much energy is released when an earthquake occurs. It is derived from the stiffness or rigidity of the rock mass around the fault rupture zone, the length of the fault that moved and the cross sectional area of the fault zone. Seismologists can also estimate its value based on the amplitude of seismic waves recorded on a seismometer.
The Richter scale (currently used to measure small and medium strength earthquakes with magnitudes below 7.0 - larger earthquakes magnitudes are measured using the moment magnitude scale as described above) is also a measure of the amount of energy released by an earthquake and is derived based on the maximum amplitude of the seismic waves as recorded on seismometers.
the power of the earthquake, force, vibration caused by the earthquake is known as the magnitude of the earthquake
then it is a major earthquake
A low earthquake is 1-3 magnitude, a medium earthquake is 4-6 magnitude and a high earthquake is 7+ magnitude.No. A 7.0 magnitude quake would be considered a "major" quake.Here is the scale of earthquake magnitude classes:ClassMagnitudeGreat8 or moreMajor7 - 7.9Strong6 - 6.9Moderate5 - 5.9Light4 - 4.9Minor3 -3.9

Above 8-9 magnitude can cause severe earthquake....
The Richter Scale measures the magnitude of an earthquake which is another way of describing the energy released in the earthquake.
12is the biggest magnitude of an earthquake.
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.
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.
