- The Richter Scale is a Magnitude scale-it is used to calculate the magnitude of small and medium sized earthquakes (those with a magnitude less than 7). The other scales mos … t commonly used for recording Earthquakes are the Moment Magnitude Scale and the Modified Mercalli Intensity Scale.

Moment magnitude scale The moment magnitude scale (abbreviated as MMS; denoted as MW or M) is used by seismologists to measure the size of earthquakes in terms of the energy released. The scale was developed in the 1970s to succeed the 1930s-era Richter magnitude scale (ML).

What are the different scales used to measure the magnitude of earthquakes? How do they differ? The Moment Magnitude Scale. Unfortunately, many scales, such as the Richter scale, do not provide accurate estimates for large magnitude earthquakes. Today the moment magnitude scale, abbreviated MW, is preferred because it works over a wider range of earthquake sizes and is applicable globally.

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.

Richter scale Richter scale [(rik-tuhr)] A scale used to rate the intensity of earthquakes. The scale is open-ended, with each succeeding level representing ten times as much energy as the last. A serious earthquake might rate six to eight, and very destructive quakes rate higher.

Moment magnitude scale This scale was based on the ground motion measured by a particular type of seismometer (a Wood-Anderson seismograph) at a distance of 100 kilometres (62 mi) from the earthquake's epicenter.

What Is the Difference Between the Richter and Mercalli Scales? The Richter and Mercalli scales are both measures of earthquake severity, but the Richter scale is much more commonly used. The scientific nature of the Richter scale is based on the maximum amplitude of a wave recorded from an earthquake combined with the distance of the instrument from the epicenter of the quake.

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

The San Andreas Fault As the Richter scale does not adequately differentiate between the largest earthquakes, a new moment magnitude scale is being used by seismologists to provide a better measure. On the moment magnitude scale, the San Francisco earthquake is estimated at magnitude 7.7 compared to an estimated Richter magnitude of 8.3.

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.

Earthquake The power of an earthquake is measured using a seismometer. A seismometer detects the vibrations caused by an earthquake. It plots these vibrations on a seismograph. The strength, or magnitude, of an earthquake is measured using the Richter scale. The Richter scale is numbered 0-10. Earthquakes measuring just one or two on the scale are very common and can happen everyday in places like San Francisco.

Difference Between Richter Scale and Mercalli Scale Thus it is known for its other term “cataclysmic level.”. Summary: 1.The Richter scale measures the seismic activity magnitude of an earthquake and other areas that can be measured numerically. 2.The Mercalli scale measures the intensity of the earthquake. 3.The Mercalli scale is an older scale that predates the Richter scale. 4.The Richter scale is more commonly used than the Mercalli scale. 5.The Richter scale is more objective as opposed to the more subjective Mercalli scale.

Measuring Earthquakes The magnitude of an earthquake, usually expressed by the Richter Scale, is a measure of the amplitude of the seismic waves. The moment magnitude of an earthquake is a measure of the amount of energy released - an amount that can be estimated from seismograph readings. The intensity, as expressed by the Modified Mercalli Scale, is a subjective measure that describes how strong a shock was felt at a particular location. The Richter Scale, named after Dr. Charles F. Richter of the California Institute of Technology, is the best known scale for measuring the magnitude of earthquakes.

Measuring earthquake magnitude and intensity Earthquakes can be measured in two ways. One method is based on magnitude—the amount of energy released at the earthquake source. The other is based on intensity—how much the ground shakes at a specific location. Although several scales have been developed over the years, the two commonly used today in the United States are the moment magnitude scale, which measures magnitude (M), or size, and the Modified Mercalli scale, which measures intensity.

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 Richter scale is logarithmic, meaning that whole-number jumps indicate a tenfold increase. In this case, the increase is in wave amplitude.

5.2 earthquake hits Southern California -- are more to come? Earthquakes today are more commonly measured by moment magnitude, a scale based on the amount of seismic energy released by the quake. In the magnitude scale, each increase of one whole number translates to 32 times more energy. Sources: CNN, US geological survey, California Institute of Technology (Caltech)

1960 Valdivia Earthquake or Great Chilean Earthquake Its waves reached Hawaii in 15 hours and Japan in 22 hours. The 1960 Valdivia earthquake or Great Chilean Earthquake of Sunday, 22 May 1960 is to date the most powerful megathrust earthquake ever recorded on Earth, rating 9.5 on the moment magnitude scale. Megathrust earthquakes generate tsunamis (known as teletsunamis) that can cross entire oceans.

Unsupervised Classification - Clustering Next: Hierarchical Classifiers Up: classification Previous: Some special cases Unsupervised Classification - Clustering. A clustering algorithm groups the given samples, each represented as a vector in the N-dimensional feature space, into a set of clusters according to their spatial distribution in the N-D space. Clustering is an unsupervised classification as no a priori knowledge (such as samples of known classes) is assumed to be available. The K-Means Algorithm. Step 1. Randomly choose initial cluster centers from the given sample set (e.g., the first samples of the sample set). Set ; Step 2.

Charles F. Richter Facts At the time, the only way to rate shocks was a scale developed in 1902 by the Italian priest and geologist Giuseppe Mercalli. The Mercalli scale classified earthquakes from 1 to 12, depending on how buildings and people responded to the tremor.harles F. Richter (1900-1985) was one of the developers of the Richter Scale which is used to measure the magnitude of earthquakes. Charles F. Richter is remembered every time an earthquake happens.

How does the Mercalli scale measure an earthquake? Answer by SBDW1 _. Confidence votes 23.9K. The Mercalli scale allocates a value to an earthquake based on the perceived shaking in a specific area as well as the damage to buildings and infrastructure that has occurred.
