SOLUTION: 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 19

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?
