 of an earthquake is defined as  . Here
. Here  is the Intensity of the earthquake and
 is the Intensity of the earthquake and   is the intensity of standard earthquake.
 is the intensity of standard earthquake.
        We have an earthquake that is 10 times more intense than a standard earthquake. Let us denote the intensity of the earthquake as  .
