← GeographyWhich risk increases when groundwater extraction weakens a strike-slip fault zone?
A)Increased frequency of induced seismicity✓
B)Decreased volcanic eruption intensity
C)Reduced geothermal energy production rates
D)Accelerated chemical weathering of bedrock
💡 Explanation
When groundwater withdrawal reduces pore pressure, the effective normal stress on a strike-slip fault increases, reducing frictional resistance and promoting fault slip, leading to induced seismicity. Therefore increased seismicity risk escalates, rather than changes in volcanic activity, energy production, or weathering rates which depend on other geological mechanisms.
