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.

Is a 7.0 earthquake medium 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

What earthquake magnitude will cause sever damage?
Above 8-9 magnitude can cause severe earthquake....
A Richter scale measures the what of an earthquake?
The Richter Scale measures the magnitude of an earthquake which is another way of describing the energy released in the earthquake.
What are the biggest earthquake magnitudes?
12is the biggest magnitude of an earthquake.
What is an earthquake's magnitude a measure of?
An earthquake's magnitude is a measure of how strong it is
Another word for an earthquake's strength is what?
Another word for an earthquake's strength is magnitude. Magnitude is a measure of the size of the seismic waves produced by an earthquake.
How much larger is an earthquake with a magnitude of 9 than an earthquake with a magnitude of 4?
An earthquake with a magnitude of 9 is 10,000 times larger in amplitude than an earthquake with a magnitude of 4 on the Richter scale. This means that the energy released by a magnitude 9 earthquake is significantly greater than that of a magnitude 4 quake.
What was the magnitude of the earthquake?
7.2 magnitude
What word describes the strength of an earthquake?
The strength of an earthquake is measured by its magnitude, which indicates the amount of energy released at the earthquake's source. Earthquake magnitude is typically reported on the Richter scale or the moment magnitude scale.
What is the highest ranked magnitude of an earthquake in the US?
There was a 9.2 magnitude earthquake in Prince William Sound, Alaska in 1964.
What magnitude was the earthquake that hit Chile?
The Earthquake of February 27,2010 had a magnitude of 8.8
What was the magnitude of the recent earthquake in haiti?
The magnitude of Haiti's recent earthquake was 7.0
How much greater is a magnitude 7.0 earthquake over a 6.0 earthquake?
The magnitude of an earthquake is measured on a logarithmic scale, so a magnitude 7.0 earthquake is 10 times stronger than a magnitude 6.0 earthquake in terms of the energy released. This means that the amplitude of ground shaking in a magnitude 7.0 earthquake would be significantly greater than in a magnitude 6.0 earthquake.
Why is 6.0 magnitude earthquake so much more destructive than a 5.0 magnitude 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.
Why is a 6.0 magnitude earthquake so much more destructive than a 5.0 magnitude 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.
Which earthquake had a magnitude of 9.5?
The 1960 Valdivia earthquake in Chile had a magnitude of 9.5. The largest recorded in human history.
