The earthquakes that are generated due to the explosion of chemical or nuclear devices are known as:
Show answer & explanation
Correct answer: D
Explanation
The correct Answer is option 4 i.e. Explosion earthquakes.
Explosion earthquakes occur due to man-made explosions, such as chemical or nuclear detonations. These artificial shocks release a sudden burst of energy into the Earth’s crust, producing seismic waves similar to natural earthquakes but usually of smaller magnitude and localized impact. Scientists often use seismic monitoring to differentiate between natural and explosion-induced tremors.
Other options:
-
Collapse earthquakes: Caused by the collapse of underground mines or caves.
-
Reservoir-induced earthquakes: Triggered by the filling of large dams or reservoirs.
-
Tectonic earthquakes: Result from movement of Earth’s tectonic plates.
