Question

Which of the following statements is/are correct regarding various scales used for measuring the earthquake?

1. Richter scale measures magnitude of earthquake whereas Mercalli scale is used to measure the intensity of earthquake.

2. Magnitude of earthquake depends on the destruction caused by earthquake.

3. Richter scale is a logarithmic scale.

Choose among the options given below:

• A. Only 1 is correct
• B. 2 and 3 are correct
• C. 1 and 3 are correct
• D. All are correct

Answer 1

The correct option is C

1 and 3 are correct

The Richter magnitude scale (also Richter scale) assigns a magnitude number to quantify the energy released by an earthquake. The Richter scale, developed in the 1930s, is a base-10 logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to arbitrary, minor amplitude.
