Question

The Richter scale measures the magnitude, M, of an earthquake as a function

of its intensity, I, and the intensity of a reference earthquake, Io.
M = log()
What is the approximate intensity of an earthquake with a Richter scale
magnitude of 4.8? Use a reference intensity of 1.

A. 0.681
B. 6,492,506
C. 660,057
D. 63,097

Answer 1

Answer: D. 63,097

Explanation:

Answer: D. 63,097

The formula for the Richter scale is M = log(I/Io), where I is the intensity of the earthquake and Io is the reference intensity. To calculate the intensity of an earthquake with a magnitude of 4.8, we can rearrange the equation to solve for I. I = Io*10^M, so in this case I = 1*10^4.8 = 63,097.
