A number of scales are used to measure earthquakes. These are broadly split into two main types. Magnitude scales and intensity scales.
Magnitude scales give an indication of the amount of energy released during an earthquake and intensity scales give an indication of the sevirity of ground shaking and resultant damage in a given location.
For more information on these, please see the related questions.

Describe the scales that scientists use to measure the magnitude of an earthquake?
The most commonly referred to scale by the press and the public is the Richter scale for measuring earthquake magnitude. However this was actually replaced in the 1970s by the Moment Magnitude scale which is the magnitude scale favoured and in use by seismologists.
A kind of scale used to measure the measure the amount of seismic energy released by an earthquake?
Seismometers measure the amplitude of seismic waves as well as the velocity and acceleration of the grounds surface. This allows seismologists to estimate the magnitude of an earthquake (the amount of energy released). From the energy emission per unit time they can estimate the power of the earthquake.
What was the Japan Earthquake 2011 on the moment magnitude scale?
Magnitude of the 2011 Japan earthquake on moment magnitude scale is 9.0.The use of the Richter magnitude scale has largely been replaced by the moment magnitude scale in most countries. The United States Geological Survey (USGS), for example, uses the moment magnitude scale designated as MMS or Mw to measure all large earthquakes.UPDATE: Official magnitude was updated to 9.1 on Nov 7, 2016.
Which scale would be used to tell how much an earthquake damage was done to homes and other buildings?
They could use the information from the seismic wave scale
What measure do scientists use to see what amount of earthquake releases is magnitude?
Scientists use the Richter scale or the moment magnitude scale (Mw) to quantify the amount of energy released by an earthquake, referred to as its magnitude. The moment magnitude scale is now more commonly used as it provides a more accurate measurement, especially for larger earthquakes, by considering the fault area and the amount of slip. Magnitude is a logarithmic measurement, meaning that each whole number increase represents a tenfold increase in measured amplitude and approximately 31.6 times more energy release.
What system do geologists use today for rating the magnitude of an earthquake?
Geologists use the moment magnitude scale (Mw) to rate the magnitude of an earthquake today. This scale takes into account the seismic moment, which provides a more precise measurement of an earthquake's size compared to the Richter scale.
What scale did Charles Richter use to measure strength?
Earthquake
What scale do scientists most often use today to express the magnitude of an earthquake?
Scientists most often use the Richter scale or the moment magnitude scale to express the magnitude of an earthquake. These scales measure the energy released by an earthquake and provide a numerical value to indicate its intensity.
How do scientists measure the size of earthquakes?
Scientists use seismographs to measure the magnitude of earthquakes. Seismographs detect the seismic waves generated by an earthquake, and the amplitude of these waves is used to calculate the earthquake's size. The most common scale used to measure earthquake size is the Richter scale or the moment magnitude scale.
Do you still use the richtor scale?
Yes we still use the richtor scale today,, to find the force of the earthquake.
What do you use to measure the power of an earthquake?
The power of an earthquake is measured using a seismometer to record the seismic waves produced by the earthquake. The magnitude of an earthquake is typically measured using the Richter scale or moment magnitude scale.
What evidence do geolgists use to rate an earthquake on the moment magnitude scale?
They measure the amplitude of the L waves to rate the earthquake.
How do you detect the magnitude of an earthquake?
You use a seismometer. Then, measure the magnitude according to the Richter scale.
Describe the scales that scientists use to measure the magnitude of an earthquake?
The most commonly referred to scale by the press and the public is the Richter scale for measuring earthquake magnitude. However this was actually replaced in the 1970s by the Moment Magnitude scale which is the magnitude scale favoured and in use by seismologists.
What scale do seismologists use to indirectly measure the magnitude of an earthquake?
Seismologists commonly use the Moment Magnitude Scale (Mw) to indirectly measure the magnitude of an earthquake. This scale calculates the energy released by an earthquake by analyzing seismic waves recorded on seismographs, taking into account factors such as the area of the fault that slipped and the amount of slip along the fault. It provides a more accurate measure of large earthquakes compared to earlier scales like the Richter scale.
Which scale would a geologist use to estimate the total energy released from an earthquake?
A geologist would typically use the Richter scale or the moment magnitude scale (Mw) to estimate the total energy released from an earthquake. The moment magnitude scale is more commonly used today as it provides a more accurate measure of an earthquake's size, especially for larger events. Both scales quantify the energy release based on seismic wave amplitude and other geological factors.
How is the strength of an earthquake measured?
The strength of an earthquake is typically measured using the moment magnitude scale (Mw), which takes into account the seismic energy released by the earthquake. This scale provides a single number that represents the overall size of the earthquake. Another commonly used scale is the Richter scale, which measures the amplitude of seismic waves.
