Question

What is the Magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? Round to the nearest tenth.

The answer is 3 (B) on edge.

Answer 1

Explanation:

We need to find the magnitude of an earthquake a 1000 times more intense than a standard earthquake

Be

S, the intensity of a "standard"

earthquake,

I intensity of new earthquake

I=1000*s

Then,

M=Log (I/S)

M=Log (1000*s/s)

M=Log (1000) = 3

The answer = 3
