Question 1065155: Earthquake intensity, I, is given by the equation
I=Io(10)^m, where m is the magnitude measured to the nearest tenth on the Richter scale and Io is the reference intensity.
In 1906, the San Francisco Bay area had an earthquake with a magnitude of 7.8 on the Richter scale.
What is the magnitude of an earthquake that is 158 times less intense than the 1906 San Francisco Bay earthquake?

So the 1906 quake,
I=I%5Bo%5D%2A10%5E%287.8%29
For a quake 158 times less intense,
