← GeographyWhich risk increases along strike-slip faults when subsurface pressure declines?
A)Convergent plate boundary formation
B)Induced seismicity occurrence✓
C)Enhanced geothermal gradient
D)Increased metamorphic rock production
💡 Explanation
Induced seismicity increases because reduced fluid pressure near a fault decreases effective normal stress, therefore frictional strength on the fault surface weakens, easing slip when shear stress changes, rather than large tectonic shifts.
