Question

Which of the following is used to quantify the energy that is released during an earthquake?

• A. Seismograph
• B. Seismogram
• C. Richter scale
• D. Damper

Hint:

Richter scale measures earthquake magnitude; each unit increase represents a 10-fold amplitude increase.

Answer 1

The Correct Option is C

To determine which option quantifies the energy released during an earthquake, let's analyze each choice:

1. Seismograph:
A seismograph is an instrument that detects and records seismic waves (ground motions) caused by earthquakes. While it measures the waves, it does not directly quantify the energy released.

2. Seismogram:
A seismogram is the graphical output or record produced by a seismograph. It shows the seismic wave data but does not quantify energy.

3. Richter scale:
The Richter scale is a logarithmic scale used to measure the magnitude (size) of an earthquake. It quantifies the energy released by the earthquake at its source, making it the correct answer.

4. Damper:
A damper is a device used in engineering (e.g., buildings, bridges) to absorb seismic energy and reduce vibrations during an earthquake. It does not measure or quantify energy release.

Final Answer:
The Richter scale is used to quantify the energy released during an earthquake.
