Essay
On the Richter scale, the magnitude R of an earthquake is given by the formula where I is the intensity of the earthquake being measured and
is the standard reference intensity.
What is the magnitude of an earthquake that has intensity 10 millions times that of ?
__________
Suppose an earthquake is measured with a magnitude of 5 on the Richter scale with an error of at most 2%.Use differentials to find the error in the intensity of the earthquake.
