Earthquake Intensity

Commonly the Richter scale is utilized to measure the intensity of an earthquake. There are several different ways of computing this depend on a variety of different quantities. We will take a quick look at the formula which uses the energy released during an earthquake.

If E refer for the energy released, measured in joules, at the time of  an earthquake then the magnitude of the earthquake is provided by,

                                      M = 2/3  log ( E  /E_o)

where E  = 10^4.4  joules.
