Question

How much greater is the shaking produced by a magnitude 8 earthquake than a magnitude 5 earthquake using the Richter Scale?

Answer 1

Answer: The correct answer is Option D.

Explanation: Richter scale is the scale which is used to observe the magnitude of earthquake with the help of seismographic oscillations.

For every higher level, the intensity of earthquake is 10 times more than the previous level.

Shaking produced by magnitude 8 is three level higher than the magnitude 5, which means that intensity will be = (10 × 10 × 10) = 1000 times greater.

Hence, the correct answer is Option D.

Answer 2

The shaking produced by a magnitude 8 earthquake is 3000 times greater than a magnitude 5 earthquake using a Richter scale. The answer is letter C. As the number in the Richter scale increases, the magnitude of earthquake also increases.
