This is known as seismic moment (M0 - which has the unit of dynes/cm =where 1 dyne/cm = 1x10-7 N/m) which is a measure of the total energy released during an earthquake and is derived based on the elastic moduli of the crust where the earthquake occurred, the length of the slip surface and the cross sectional area of the slip surface as follows:
M0 = G x AFx DF
Where:
G = Shear modulus of the rock mass
AF = Area of the rupture along the fault
DF = average displacement on AF
For an explanation of how this value is used to determine an earthquakes magnitude, please see the related question.
What else can I help you with?
Magnitude is an earthquake's what?
The magnitude of an earthquake is caluated to measure the amount of energy released during the earthquake.
What tool is used to measure earthquake's energy?
The Richter scale is a tool used to measure the energy released by an earthquake. It calculates the earthquake's magnitude based on the amplitude of seismic waves recorded on seismographs.
What is earthquake magnitude and how is it measured?
Earthquake magnitude is a measure of the energy released during an earthquake. It is typically measured using the Richter scale or the moment magnitude scale. These scales assign a numerical value to quantify the seismic energy released, with each whole number increase representing a tenfold increase in amplitude.
What do values on the Richter scale express?
The values on the Richter scale express the magnitude of an earthquake, which is a measure of the energy released at the earthquake's source. The scale is logarithmic, meaning that each whole number increase represents a tenfold increase in the amplitude of seismic waves and approximately 31 times more energy release.
What is the strength of an earthquake called?
The strength of an earthquake is called its magnitude. This is a measure of the size of the earthquake based on the energy released at the source. It is typically calculated using the Richter scale or the moment magnitude scale.
Magnitude is an earthquake's what?
The magnitude of an earthquake is caluated to measure the amount of energy released during the earthquake.
What term means the measure of energy released by an 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.
What is an earthquake's magnitude a measure of?
An earthquake's magnitude is a measure of how strong it is

What is the scale used to measure the amount of sesmic energy released by an earthquake called?
Richter scale.
What do values on the Richter scale express?
The values on the Richter scale express the magnitude of an earthquake, which is a measure of the energy released at the earthquake's source. The scale is logarithmic, meaning that each whole number increase represents a tenfold increase in the amplitude of seismic waves and approximately 31 times more energy release.
What is another variable besides damage that scientists measure to jugde the strength of an earthquake?
Scientists also measure the magnitude of an earthquake, which represents the total energy released at the source. Magnitude is typically measured on the Richter scale or the moment magnitude scale.
