Question

The magnitude R, measured on the Richter scale, of an

earthquake of intensity I is defined as R= log
where lo is a minimum intensity used for
comparison. If the intensity of an earthquake was 106.61
lo. what was the magnitude on the Richter scale?
The magnitude of the earthquake was . (Simplify your answer.)

Answer 1

6.5

Explanation:

calculating for magnitude of quake in richer scale R

I = the quake's intensity = 106.5*I0

I0 = minimum intensity of earthquake

R = log(106.5*I0/I0)

R = log(106.5)

R = 6.5
