How is the magnitude of an earthquake measured
The magnitude of an earthquake can be measured using the Richter scale which calculates the magnitude given by the following formula, $$\displaystyle M=\log \left( \frac{I}{S}\right) $$ where, {eq}\displaystyle I {/eq} - Intensity of the earthquake measured by seismograph {eq}\displaystyle S {/eq} - Intensity of a standard earthquake.The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included in the magnitude formula to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquakes. ...

Richter Scale The earliest earthquake measurements were simple descriptions called intensity ratings ... Instead of tenfold jumps with each increase in magnitude, ...The magnitude of an earthquake is measured on the Richter scale as a logarithm of the intensity of the shock wave. For magnitude R and intensity I, the formula is R = log(I). The 1933 earthquake in Long Beach measured 6.2 on the Richter scale. The Palm Springs earthquake in August 28, 2001 measured 3.4 on the scale.1 day ago · Nepal’s National Earthquake MonitoringThe earthquake events are measured either accordi Magnitude describes the overall size of an earthquake as an event in the earth. 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. The earthquake events are measured either accord Seismic waves and factors related to the shifting ground determine an earthquake’s magnitude, as measured through 10 on the scale most commonly used to describe quakes. Song and his colleagues theorized that if they could measure th
An earthquake of magnitude 7 is 10 x 10 = 100 times strong than an earthquake of magnitude 5. An earthquake of magnitude 8 is 10 x 10 x 10 = 1000 times stronger than an earthquake of magnitude 5.
