Which risk increases when multiple large dams are constructed in seismically active zones?

💡 Explanation

When large dams are built in seismically active zones, the increased water pressure in reservoirs alters the effective stress along existing faults because the fluid pressures lowers the frictional resistance of those faults. Therefore induced seismicity results, rather than downstream landslides, saltwater intrusion, or glacier melting which depend on different climate and geographic factors.
