Question

On richter scale, an increase in the magnitude of 4 units means that the destructive amplitude of the earthquake increases by 4 times.

• A. True
• B. False

Answer 1

The correct option is B

False

Richter scale is not linear. In fact, an increase of 2 in magnitude means 1000 times more destructive energy. For example, an earthquake of magnitude 6 has thousand times more destructive energy than an earthquake of magnitude 4.
