The Richter, The Mercalli, and The Moment Magnitude Scale. the richter scale goes from 1 to 9 1 meaning that you can barely feel the earthquake and 9 meaning that it was the most powerful earthquake that you can have also with a 9 you can defiantly feel the earthquake the mercalli scale or the modified mercalli scale is used to measure the intensity of an earthquake

Earthquakes Intensity scales, like the Modified Mercalli scale and the Rossi-Forel scale, measure the amount of shaking at a particular location. So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce. Magnitude scales, like the Richter magnitude scale and moment magnitude, measure the size of the earthquake at its source.

What is the use of the Mercalli Scale? Mercalli scale is or the MMI scale as it is known today is used in reference to damage inflicted by an earthquake. So it is called an Intensity Scale. Unlike the universalised as moment-magnitude scale of Richter (which is numbered in terms of energy released by an earthquake), the MMI scale is a local scale for an area.

Richter Scale The Richter scale is a base-10 logarithmic scale, meaning that each order of magnitude is 10 times more intensive than the last one. In other words, a two is 10 times more intense than a one and a three is 100 times greater. In the case of the Richter scale, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake is 10 times greater than in a level 5 earthquake, and the amplitude increases 100 times between a level 7 earthquake and a level 9 earthquake.

Richter scale A logarithmic scale used to express the amount of energy released by an earthquake. Its values typically fall between 0 and 9, with each increase of 1 representing a 10-fold increase in energy. [After Charles Francis Richter, (1900-1985), American seismologist.]

How Earthquakes Work The most common standard of measurement for an earthquake is the Richter scale, developed in 1935 by Charles F. Richter of the California Institute of Technology. The Richter scale is used to rate the magnitude of an earthquake -- the amount of energy it released. This is calculated using information gathered by a seismograph.

The Modified Mercalli Scale of Earthquake Intensity The Modified Mercalli Scale of Earthquake Intensity In seismology a scale of seismic intensity is a way of measuring or rating the effects of an earthquake at different sites. The Modified Mercalli Intensity Scale is commonly used in the United States by seismologists seeking information on the severity of earthquake effects. Intensity ratings are expressed as Roman numerals between I at the low end and XII at the high end.

Richter scale The scale has no upper limit but usually ranges from 1 to 9. Because it is logarithmic, an earthquake rated as 5 is ten times as powerful as one rated as 4. An earthquake with a magnitude of 1 is detectable only by seismographs; one with a magnitude of 7 is a major earthquake. The Richter scale is named after the American seismologist Charles Francis Richter (1900-1985).

What Is the Difference Between the Richter and Mercalli Scales? Giuseppe Mercalli invented the Mercalli intensity scale in 1902 as a way to measure the effects of an earthquake. The scale is based off of the observations of the people who experienced the earthquake.

What is the use of the Mercalli Scale? It is not based on first physical principles, but is, instead, empirically based on observed effects. The Mercalli scale quantifies the effects of an earthquake on the Earth's surface, humans, objects of nature, and man-made structures on a scale from I (not felt) to XII (total destruction). Values depend upon the distance from the earthquake, with the highest intensities being around the epicentral area.

Earthquakes: Facts The Richter Scale measures magnitude, the amount of energy released by an earthquake by measuring how big a shock wave is. Each number on the scale is 10 times more powerful than the number below it. A magnitude 3 earthquake is ten times greater that a magnitude 2 and is easily felt. An earthquake that registers 6 or more is considered a major quake.

What are the different scales used to measure the magnitude of earthquakes? How do they differ? The Richter Scale. Figure 1 - Charles Richter studying a seismogram. There are a number of ways to measure the magnitude of an earthquake. The first widely-used method, the Richter scale, was developed by Charles F. Richter in 1934.nother way to measure the strength of an earthquake is to use the Mercalli scale. Invented by Giuseppe Mercalli in 1902, this scale uses the observations of the people who experienced the earthquake to estimate its intensity. The Mercalli scale isn't considered as scientific as the Richter scale, though.

Cochise College Student Papers in Geology Seismologists use two main devices to measure an earthquake: a seismograph and a seismoscope. The seismograph is an instrument that measures seismic waves caused by an earthquake. The seismograph has three main devices, the Richter Magnitude Scale, the Modified Mercalli Intensity Scale, and the Moment-Magnitude Scale.

What is the difference between the Richter scale and the Mercalli scale? In the case of the Richter magnitude this is based on the amplitude of the seismic waves measured on a seismometer and the distance of the seismometer station from the epicentre of the earthquake. The magnitude value should be the same for a given earthquake no matter where it is recorded.

The Severity of an Earthquake Adjustments are included for the variation in the distance between the various seismographs and the epicenter of the earthquakes. On the Richter Scale, magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 might be computed for a moderate earthquake, and a strong earthquake might be rated as magnitude 6.3.

Earthquakes: seismology & measurement The severity of an earthquake is called its magnitude. Various scales were proposed to measure the magnitude of earthquakes until 1935, when the Richter Scale was developed by a seismologist named Conrad Richter to measure the intensity of the seismic waves.
