उत्तर
Earthquakes can occur due to the following reasons:
- Volcanic eruptions – These are caused by sudden eruptions and the movement of magma beneath the Earth’s crust.
- Meteors falling on the Earth’s surface – These are rare events, but the impact of large meteors can cause earthquakes.
- Underground explosions (such as nuclear tests) – These are human-induced earthquakes, occurring due to explosions underground.
- Collapse of underground structures (like mines and tunnels) – These are caused by the sudden collapse of these structures, leading to small earthquakes.
- Mining and the construction of big dams – These are human activities that increase stress and pressure in rocks, leading to earthquakes.
