Question

Explain four human causes of Earthquake.

Answer 1

1. Underground nuclear tests; when nuclear bombs are detonated below the surface, they cause a lot of vibrations which are felt on the earth’s surface.
2. Construction of large reservoirs; water on dams or man made lakes exert a lot of weight on the ground. This can trigger earthquakes.
3. During quarrying; rocks are blasted using explosives in order to reduce their sizes. This cause vibrations to be felt in surrounding areas.
4. Movement of heavy trains; when they pass by, they vigorously shake the ground and these vibrations are felt as tremors nearby.
