Yes. The Mercalli intensity scale measures the effect of the earthquake on people and structures, and the intensity value will differ depending on how far you are from the epicenter.
For instance, a 5.5 magnitude earthquake may be damaging (intensity VII) around the epicenter, but 300 miles away it may be barely felt (intensity II).
The mercalli scale measures the intensity of an earthquake, where the Richter scale measures the magnitude.
Also you have to consider where the earthquake occurred. you can have a 9.0 quake in the middle of the Australian outback but there is hardly anybody there so you would have a low mercalli scale reading. If you had that same quake in San Francisco then you are going to have a seriously high number on the mercalli scale

∙ 14y agoThe Modified Mercalli scale assigns a value to an earthquake from I to XII depending on it's intensity, with I being the lowest (only recorded by seismometers, not felt by humans) and XII being the highest (representing total destruction of all buildings).
Mercalli values are derived from a number of sources including witness reports of the perceived ground shaking in their location, the damage to structures and also measurements of the ground accelerations from seismometers (included to attempt to reduce the subjectivity of the scale due to it's reliance on human witnesses).

∙ 13y agoIt depends what you mean by the MMS scale. This could either be the Moment Magnitude scale or the Modified Mercalli scale.
The Modified Mercalli scale was designed to measure the intensity of an earthquake whereas the Richter scale was used to measure the magnitude of an earthquake.
Magnitude is the amount of energy released by an earthquake and is the same no matter where it is measured. Intensity is a measure of the severity of ground shaking and damage caused by an earthquake at a specific point and so can vary depending on the specific local ground conditions and the distance from the epicentre where it is measures.
The Moment Magnitude scale like the Richter scale is used to find the amount of energy released in an earthquake. However they use different methods to calculate this value. Using Richter's technique, the magnitude is assessed by the amplitude of seismic waves as measured by a seismometer (after applying a correction based on the distance of the seismometer station from the epicentre). The Moment magnitude scale is based on deriving the "seismic moment" of the earthquake. This is calculated based on the cross sectional area of the fault surface that slipped during the earthquake, the size of the fault displacement and the elastic properties of the rock mass surrounding the fault. This difference in measuring techniques normally accounts for the difference in Moment and Richter magnitudes for a given earthquake.

∙ 8y agoBecause an earthquakes magnitude is different from its intensity. Intensity measures the affects of an earthquake at earths surface. Magnitude measures how much energy is released by an earthquake.

An earthquake will be given one number on the Richter scale but more than one on the mercalli scale why is this?
The Richter scale measures the strength of an earthquake, this is always the same value, no matter where you are. The Mercalli intensity scale measures the effect of the earthquake on people and structures, and the intensity value will differ depending on how far you are from the epicenter. For instance, a 5.5 magnitude earthquake may be damaging (intensity VII) around the epicenter, but 300 miles away it may be barely felt (intensity II).
How is magnitude and intensity scale in earthquakes different?
Magnitude regards the size of the event of phenomena, whereas intensity refers to amounts over time. Intensity is akin to frequency. For example when measuring earthquakes, Richter scale gauges its force through magnitude, and its intensity is frequency of resonation felt.
Difference between intensity and magnitude?
Magnitude is a measure of the energy released by the earthquake - it is an absolute value and does not vary with where it is measured. Intensity measures the strength of the shaking at a particular location and will vary with distance, substrate conditions and other factors. It is a subjective measure which depends on observation, not measurement. The reference below sets it all out for you.Is also an answer but here's another answer:This is my answer:D(Magnitude / Intensity Comparison)(Magnitude and Intensity measure different characteristics of earthquakes. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs while Intensity measures the strength of shaking produced by the earthquake at a certain location. Intensity is determined from effects on people, human structures, and the natural environment.)
Why value of 'g' decreases when you go inside the earth?
Because the value of "g" varies directly with the sum of the masses of the two bodies acted upon by the force of gravity. If you go inside the earth, only part of the mass of the earth will be attracting you toward its center; the mass of the part of the earth that is farther from the center than you are will be attracting you away from the center. If it were possible to reach the center of the earth, the value of "g" would reach zero because the mass of the earth would be acting upon equally you in all directions.
What is the value of Earth's gravitational field at the center of the Earth?
In the cavity at the center of the Earth, your weight would be zero, because you would be pulled equally by gravity in all directions. - The gravitational field of Earth at its center is zero.
How the energy of a quake travels through earth and damages the surface?
The energy is produced at the hypocentre or core and propogates towards the crust of the earth. That surface point is known as epicentre. The max richter scale value for a earth quake is just more than 9. There is no limit to max value.
Which scale is used to describe the intensity of an eartyhquake?
It's called the Richter scale. Numbered from 1 to 10, each number is ten times the previous. So - a quake with a value of 3 is 100 times more powerful than a level 1 quake.
Hue value and intensity are properties of?

What intensity is the weakest?
The moment magnitude scale goes as low as 0.0 and any quake that released less than 63 kilojoules of energy would registrer as 0.0 on the Richter scale. Quakes with a Richter value of 2.0 or less were classified as "microquakes" and were almost never detected by human senses.
What can you spell with the letters qeevakl?
The longest word is "leave." (*With a U, you could spell quake and value).
What is the Intensity 1 and Intensity 2?
The intensity is a number (written as a Roman numeral) describing the severity of an earthquake in terms of its effects on the earth's surface and on humans and their structures.According to Modified Mercalli Scale, 1956 version, Intensity value I means than an earthquake is Only detectable by seismographs.Intensity II means an earthquake is Felt by persons at rest on upper floors or favorably placed.Best regards, Chernishov Nikolay.
What is meant by the half value layer of a homogenous beam?
The half value layer of a homogenous beam is the thickness of the absorber that reduces the intensity of the beam to half the initial (starting) intensity.
What is the weakest earthquake intensity?
The moment magnitude scale goes as low as 0.0 and any quake that released less than 63 kilojoules of energy would registrer as 0.0 on the Richter scale. Quakes with a Richter value of 2.0 or less were classified as "microquakes" and were almost never detected by human senses.
What is the value of 1 ampere?
ampere is the unit of the electric current intensity 1ampere=1coloumb/1sec intensity=quantity/time(by seconds)
Can you please name me a few atributes of color?

What do you mean by intensity value?
The word "intensity" can be synonymous with "strength", "amplitude", or "level", as it sometimes is in colloquial speech. It is possible to define the intensity of the water coming from a garden sprinkler, but intensity is used most frequently with waves - i.e. sound or light.
What does the word intensity mean?
The word "intensity" means "strength", "amplitude", or "level." For example, one light source, being brighter, may have more intensity than a dimmer one.Without a numerical or comparative value, "intensity" suggests a higher level (more intense), e.g. he always played with intensity.
