Question

On the Richter scale, the rating R of
an earthquake can be measured by the
intensity model: R=log(1) where I is the
intensity of the shockwave. If an
earthquake measures as a 5.6 on the
Richter scale, what is the intensity of
the shockwave?

a. I = 398107.171
b. I = 56
c. I = 0.748
d. I = 1.723​

Answer 1

Answer:

The Richter scale defines the magnitude of an earthquake to be R=log(IcIn) where Ic is the intensity of the earthquake and In is the intensity of a standard earthquake. Therefore, you can write the difference of two magnitudes as R2−R1=log(I2I1).
