Which risk significantly increases when excessive groundwater extraction precedes seismic activity?

💡 Explanation

Excessive groundwater extraction increases pore pressure changes; therefore, Coulomb stress transfer can trigger increased fault slip, leading to a heightened earthquake acceleration exceedance probability, because faults are already stressed. This is Coulomb stress transfer, rather than liquefaction, which relates to soil stability.
