Differbetween
The Mercalli scale bases its measurement on the observed effects of the earthquake and describes its intensity. It is a linear measurement. On the other hand, the Richter scale measures the seismic waves, or the energy released, causing the earthquake and describes the quake's magnitude.

What is the difference between Richter magnitude moment magnitude and the Modified Mercalli Intensity Scale MMI )?
Richter Scale. While the Mercalli scale describes the intensity of an earthquake based on its observed effects, the Richter scale describes the earthquake's magnitude by measuring the seismic waves that cause the earthquake.
What do the Richter and Mercalli scales measure?
Learn how the Richter scale measures magnitude and the Mercalli scale measures intensity of an earthquake. The Richter scale measures the magnitude of earthquakes, and the Mercalli scale measures... Encyclopædia Britannica, Inc.
What does the Mercalli scale measure?
The modified Mercalli intensity scale (MM or MMI), developed from Giuseppe Mercalli's Mercalli intensity scale of 1902, is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake.
What is the difference between Richter scale and magnitude?
Intensity: The severity of earthquake shaking is assessed using a descriptive scale – the Modified Mercalli Intensity Scale. Magnitude: Earthquake size is a quantitative measure of the size of the earthquake at its source. The Richter Magnitude Scale measures the amount of seismic energy released by an earthquake.
What is the weakest intensity scale?
Scales. The PEIS has ten intensity scales represented in Roman numerals with Intensity I being the weakest and Intensity X being the strongest. Delicately balanced objects are disturbed slightly.
What is the strongest intensity scale?
PHIVOLCS Earthquake Intensity Scale (PEIS)
| Intensity Scale | Shaking |
|---|---|
| IV | Moderately Strong |
| V | Strong |
| VI | Very Strong |
| VII | Destructive |
What is the formula for the Richter scale?
The Richter scale defines the magnitude of an earthquake to be R=log(IcIn) where Ic is the intensity of the earthquake and In is the intensity of a standard earthquake.
What is the max on the Richter scale?
In theory, the Richter scale has no upper limit, but, in practice, no earthquake has ever been registered on the scale above magnitude 8.6. (That was the Richter magnitude for the Chile earthquake of 1960. The moment magnitude for this event was measured at 9.5.).
Why is the Richter scale no longer used?
The Richter scale was abandoned because it worked best for earthquakes in southern California, and only those hitting within about 370 miles (600 kilometers) of seismometers. ... The moment magnitude scale captures all the different seismic waves from an earthquake, giving a better idea of the shaking and possible damage.
Does the Mercalli scale measure damage?
The Mercalli intensity scale (or more precisely the Modified Mercalli intensity scale) is a scale to measure the intensity of earthquakes. ... When there is little damage, the scale describes how people felt the earthquake, or how many people felt it.
What scale is used to measure the strength of small nearby earthquakes?
The Richter scale is most common in the United States, while worldwide, scientists rely on the Mercalli scale. The moment magnitude scale is another earthquake measurement scale used by some seismologists. All three scales provide useful information in measuring and analyzing earthquakes across the globe.
Which scale is used for measuring earthquake?
The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes. Intensity is a measure of the shaking and damage caused by the earthquake; this value changes from location to location.
