Consider the following statements:
1. The Richter scale is a logarithmic scale and so an increase of 1 magnitude unit represents a factor of 10 times in amplitude.
2. Each integer reading of the Richter scale has an energy 100 times that the previous integer reading.
Which of the statement(s) given above is/are correct?
(a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2
(a) The magnitude of intensity of energy released by an earthquake is measured by Richter Scale. The number indicating magnitude on Richter Scale ranges between 0 and 9 but infact the scale has no upper limited of number because it is a logarithmic scale. But each integer reading of the Richeter Scale has in energy 32 times of previous integer reading. So the statement is not correct.
