← GeographyWhich outcome results when subsurface salt dissolves adjacent to faults?
A)Increased frequency of induced seismicity✓
B)Reduced geyser activity near springs
C)Enhanced stability of subterranean caverns
D)Decreased landslide risk on steep slopes
💡 Explanation
Dissolution increases pore pressure, thus, brittle failure occurs more readily via pore pressure diffusion in faults, triggering induced seismicity because the effective stress decreases. Therefore, induced seismic events increase, rather than decreasing geyser activity or stabilizing subterranean structures.
