Answer:
The correct answer is - 30 times more energy was released by an earthquake.

In the Richter scale, there are integers that explain or show the amplitude of the largest wave and also show the release of energy by the earthquake. An increase in a single integer is equal to the thirty times more energy that is released by an earthquake.
Thus, the correct answer is -30 times more energy was released by an earthquake.
