Which 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.
