Q. Consider the following pairs:
Type of Earthquake Related to
1. Collapse Earthquake Large Reservoirs
2. Explosion Earthquake Nuclear Device
3. Tectonic Earthquake Fault Line
4. Volcanic Earthquake Active Volcanoes
How many of the pairs given above is/are correctly matched?
Answer: C
Notes:
Explanation: Types of Earthquakes:
- The most common ones are the tectonic earthquakes. These are generated due to sliding of rocks along a fault plane.
- A special class of tectonic earthquake is sometimes recognised as volcanic earthquake. However, these are confined to areas of active volcanoes.
- In the areas of intense mining activity, sometimes the roofs of underground mines collapse causing minor tremors. These are called collapse earthquakes.
- Ground shaking may also occur due to the explosion of chemical or nuclear devices. Such tremors are called explosion earthquakes.
- The earthquakes that occur in the areas of large reservoirs are referred to as reservoir induced earthquakes.
