← GeographyWhich seismic risk increases adjacent to dams intersecting transform faults?
A)Induced seismicity from reservoir impoundment✓
B)Liquefaction exceeding design specifications
C)Tsunami heightened by fault displacement
D)Landslides triggered fault line rupture
💡 Explanation
Increased water pressure behind dams located on transform faults enhances induced seismicity, by reducing effective stress, because fault slip is facilitated by fluid injection, resulting in more frequent, although not necessarily larger, earthquakes; therefore, option A is ideal, rather than B, C, or D which aren't linked similarly to dam effects.
