Which risk increases when groundwater extraction destabilizes a region along an existing fault line?

💡 Explanation

When groundwater extraction alters the stress regime along a fault, pore pressure changes because the effective normal stress increases, potentially triggering slip events and leading to increased frequency of induced seismicity. Therefore, induced seismicity is the main risk, rather than reduced temperature gradients, amplified magnetic anomalies or reduced soil erosion which are unrelated to fault mechanics.
