With reference to the Shindo Shaking Scale, consider the following statements: 1. The Shindo scale, used in Japan, measures the intensity of ground shaking at a particular location, rather than the total energy released by an earthquake. 2. The Shindo scale ranges from 1 to 10, with each successive level representing a tenfold increase in earthquake magnitude. Which of the statements given above is/are correct? |ForumIAS

Q. With reference to the Shindo Shaking Scale, consider the following statements:
1.The Shindo scale, used in Japan, measures the intensity of ground shaking at a particular location, rather than the total energy released by an earthquake.
2.The Shindo scale ranges from 1 to 10, with each successive level representing a tenfold increase in earthquake magnitude.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: A

Notes:

Explanation: 1 only

Statement 1 is correct: The Shindo (Japan Meteorological Agency seismic intensity) scale measures the degree of shaking experienced at a specific location. It therefore differs from earthquake magnitude scales, which quantify the energy released at the source.

Statement 2 is incorrect: The Shindo scale has 10 intensity levels: 0, 1, 2, 3, 4, 5-lower, 5-upper, 6-lower, 6-upper and 7. It is not a magnitude scale, and the levels do not represent tenfold increase in earthquake energy.
