Magnitude earthquake scale
Magnitude Types; Magnitude Type Magnitude Range Distance Range Equation Comments; Mww (Moment W-phase)(generic notation Mw) ~5.0 and larger: 1 - 90 degrees: M W = 2/3 * (log 10 (M O) - 16.1), where M O is the seismic moment. Note this is also unit-dependent; the formula above is for moment in dyne-cm. ... A magnitude for regional …Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations.

San Francisco earthquake of 1989, major earthquake that struck the San Francisco Bay Area, California, U.S., on October 17, 1989, and caused 63 deaths, nearly 3,800 injuries, and an estimated $6 billion in property damage. It was the strongest earthquake to hit the area since the San Francisco earthquake of 1906.An observer near the epicenter of an earthquake will generally experience a magnitude 3 or 4 on the Richter Scale as a mild shaking, 5 or 6 will be enough to ...1. Richter scale measures magnitude of earthquake whereas Mercalli scale is used to measure the intensity of earthquake. 2. Magnitude of earthquake depends on the destruction caused by earthquake. 3. Richter scale is a logarithmic scale. (a) Like charges attract each other.In the last ten years, environmental awareness has shot up around the world.

(Image credit: By Gustavo Bruzzone Rocco - Unknown source ... Magnitude scales, like the moment magnitude, measure the size of the earthquake at its source. An earthquake has one magnitude. The magnitude does not depend on where the measurement is made. Often, several slightly different magnitudes are reported for an earthquake. This happens because the relation between the seismic measurements and …Magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram. ….
