The Magnitude (Richter Scale)of an Earthquake Is Given by R

Short Answer

The magnitude (Richter Scale)of an earthquake is given by R = log
where I is the intensity of the earthquake and
is the intensity of a zero-level reference earthquake.
represents how many times greater the earthquake is than the reference earthquake.Find the magnitude of an earthquake that is 2,000,000 times the intensity of a zero-level earthquake.
