The scale used to measure the severity of earthquakes is called the Richter scale. The Richter scale was invented by an American seismologist named Charles Richter at the California Institute of Technology in 1935.
Know MoreThe Richter scale is a logarithmic scale that measures the intensity of seismic vibrations in the Earth’s crust. The scale is numbered from 1 to 10, with 10 representing the most severe earthquakes. The magnitude or intensity of an earthquake is measured in whole numbers and decimal fractions. Earthquakes with a magnitude of 2.0 or less are often called micro quakes, while major earthquakes usually have a magnitude of 4.5 or greater. A seismograph is the instrument used to measure these seismic vibrations.
Learn more about EarthquakesThe Richter scale is logarithmic. Each whole-number jump indicates a tenfold increase in wave magnitude and a 31.7 increase in energy released. For example, a Richter 9 earthquake has 100 times the magnitude and 1004.89 times the energy of a Richter 7 earthquake.
Full Answer >The strength of an earthquake is measured by its Moment Magnitude Scale, or MMS. The MMS measures the total energy, or seismic moment, of an earthquake. The seismic moment of an earthquake is measured based on three factors: the distance rocks slide, the area of the fault slide and the rigidness of the rocks that are broken.
Full Answer >A diagram that uses the Richter scale is used to measure the magnitude of an earthquake. When an earthquake takes place, a device called a seismograph records the earthquake's vibration, and multiple seismographs can form a coherent picture. From the resulting diagram, the earthquake's force can be determined.
