Which human activity can trigger artificial earthquakes?
A. Deforestation
B. Urbanization
C. Reservoir-induced seismicity (dam construction)
D. Air pollution
Answer (2)
Reservoir-induced seismicity, particularly from dam construction, is the main human activity that can trigger artificial earthquakes. This occurs due to changes in pressure and stress in the Earth's crust from the weight of the water in large reservoirs. Urbanization and deforestation have indirect effects, but are not direct triggers. ;
The correct answer is C: Reservoir-induced seismicity (dam construction), as this human activity directly alters pressure on fault lines, leading to artificial earthquakes. Urbanization and deforestation may have indirect effects but are not direct triggers. Air pollution is not linked to artificial earthquakes.
