The Richter scale - also called the Richter magnitude scale or Richter's magnitude scale - is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". Earthquake magnitude Definition: relative importance or significance | Bedeutung, Aussprache, bersetzungen und Beispiele An earthquake is considered to have a single magnitude. Calculating seismic moment (Ricther is no longer used) requires the following equation: > Seismic moment (Mo) = * rupture area * slip length where is the shear modulus of the crust (approx 3x10^10 N. An earthquake is shaking or trembling of the earth's surface, caused by the seismic waves or earthquake waves that are generated due to a sudden movement (sudden release of energy) in the earth's crust (shallow-focus earthquakes) or upper mantle (some shallow-focus and all intermediate and deep-focus earthquakes). Magnitude represents the total energy the earthquake radiates, and is calculated using information on how large an area moves, the distance that one side of the fault moves past the other, and the rigidity of the rock. Early estimates of earthquake size were based on non-instrumental measures of the earthquakes effects. Great earthquake.

Recent Examples on the Web Earthquakes with magnitude of 2.0 or less are called microearthquakes. Thus it is clear that magnitude is a fixed value independent of distance from the epicenter of the earthquake, whereas intensity varies and is measured differently at different places depending upon its distance from the epicenter. Morganton, N.C. A minor magnitude 2.7 earthquake was recorded Tuesday in western North Carolina, according to the United States Geological Survey. As the earthquake magnitude increases, the mean flow rates decrease due to water loss caused by leaks and breaks.
