The Moment Magnitude Scale. The Moment Magnitude Scale measures the amount of energy released by an earthquake event. It is calculated using a formula that includes the rigidity of the rock affected, the distance moved and the size of the area where movement takes place. The video on the left below explains this more fully.

The Richter Scale is a way of measuring the strength of an earthquake. It was created by seismologist Charles Richter in 1935 and is used around the world to understand how strong an earthquake was. The scale goes from 1 to 9 so if an earthquake is rated 5, that means it is 10 times stronger than an earthquake rated 4 and 100 times stronger ...earthquake is measured by the amount of ground movement that it produces. The Richter Scale has been in use for many years and is an example of a logarithmic scale. Logarithmic scales are linear scales in ‘x’ such as 1.0, 2.0, 3.0 etc, but they represent magnitude changes of 10, 100 and 1000 etc. Because natural phenomena span such a large

Charles F. Richter devised his magnitude scale in the mid-1930s while investigating earthquakes in California. He used seismographs which magnified ground motion 2800 times, and as a baseline, he defined a magnitude 0 earthquake as being one that would produce a record with an amplitude of one-thousandth of a millimeter at a distance of 100 ...Covers the instruments scientists use to measure earthquake magnitude and learn about Earth's interior. Estimated 4 mins to complete % Progress.Earthquakes can be measured in two ways. One method is based on magnitude—the amount of energy released at the earthquake source.

Step-by-step explanation: The magnitude "M" of an earthquake is defined as: (1) where I is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and S is the intensity of a “standard” earthquake, which is barely ...

Numbers make up data. For example, hurricanes are measured by category (1-5) based on wind speed. Tornadoes are measured on the Fujita scale (F1-F5) estimated by damage that is caused. Earthquakes are measured by magnitude (1-10) based on the energy released. Earthquakes occur when tectonic plates slip. This shift causes the earth to shake.Aug 25, 2014 · 7. Landers; June 28, 1992.
