What scale is used to measure the energy of an earthquake?

A magnitude scale. Formerly the Richter magnitude scale was used, but this has now been replaced by the Moment magnitude scale.


How are earthquake magnitude and intensity measured?

Earthquake magnitude is measured using a number of differing scales including the Richter scale, the moment magnitude scale and the surface magnitude scale. Intensity is measured using he Modified Mercalli intensity scale.


Why Richter Scale is Non-Linear?

The Richter scale is not a linear scale. This means that an earthquake of magnitude 6 does not have twice as destructive power as the earthquake of magnitude 3. Actually, an earthquake with magnitude 5 is ten times more destructive than an earthquake of magnitude 4. The Richter scale is a logarithmic scale.


What event's magnitude is expressed as a number on the Richter Scale?

An earthquake's magnitude is expressed as a number on the Richter Scale.


Earthquake intensity is charted on a Richter scale on a scale of 1 to?

The "Richter scale" (properly: local magnitude scale) is only accurate up to about magnitude 6 and tends to underestimate anything higher than that. The related surface magnitude scale saturates at about magnitude 8.The USGS now uses the moment magnitude scale for medium to large quakes (anything above magnitude 3.5 or so; it doesn't scale well below that). It has no theoretical upper limit, but the largest scientifically documented earthquake so far had a moment magnitude of about 9.5.

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 is the difference in the Richter scale and magnitude?

The Richter scale is a magnitude scale - it measures the amount of energy released by an earthquake. As such tit is a way of quantifying earthquake magnitude and comparing it to other earthquakes.
