Earthquakes are recorded by a seismographic network. There are many different ways to measure different aspects of an earthquake:
- The earthquake events are scaled either according to the magnitude or intensity of the shock. Magnitude is the most common measure of an earthquake's size. The magnitude relates to the energy released during the earthquake. Hence, statement 1 is not correct.
- Intensity is a measure of the shaking and damage caused by the earthquake; this value changes from location to location. The intensity scale takes into account the visible damage caused by the event. Hence, statement 2 is not correct.
- The magnitude scale is known as the Richter scale. The magnitude is expressed in absolute numbers, 0-10. The intensity scale is named after Mercalli, an Italian seismologist. The range of intensity scale is from 1-12. Hence, statement 3 is correct.

Which of the following statements is/are correct with reference to mea...
The correct answer is option C: 3 only.
- Intensity Scale:
The intensity scale measures the effects of an earthquake at a particular location. It assesses the level of shaking and the degree of damage caused by the earthquake. The intensity scale is usually represented by the Mercalli scale, which assigns a Roman numeral value to describe the effects of an earthquake. The scale ranges from I (not felt) to XII (total destruction).
- Magnitude Scale:
The magnitude scale measures the total amount of energy released during an earthquake. It quantifies the size or strength of an earthquake. The most commonly used magnitude scale is the Richter scale, which assigns a numerical value to an earthquake based on the amplitude of seismic waves recorded by seismographs. The Richter scale is logarithmic, meaning that each whole number increase on the scale represents a tenfold increase in the amplitude of the waves and approximately 31.6 times more energy released.
- Difference between Intensity and Magnitude:
It is important to note that intensity and magnitude are different measurements. Intensity describes the effects of an earthquake at a specific location, while magnitude quantifies the energy release of the earthquake. Intensity can vary depending on the distance from the epicenter and the characteristics of the local geology, while magnitude is a more objective measure of the earthquake's strength.
- Conclusion:
Therefore, the statement that is correct with reference to measuring earthquakes is that while the Richter scale measures the magnitude of the earthquake, the Mercalli scale measures the intensity of the event. The intensity scale measures the effects and damage caused by the earthquake at a particular location, while the magnitude scale measures the energy released during the earthquake.
