Which outcome occurs when groundwater weakens a fault?

💡 Explanation

ETS events become more likely because fluid pressure reduces the effective normal stress, promoting unstable slip events; thus ETS is more likely, rather than large quakes that require accumulated stress.

• Which consequence results when volcanic ash suspends high in atmosphere?
• Which risk increases following increased freeze-thaw cycles on granite?
• Which consequence results when differential weathering weakens strata?
• Which risk increases because internal pressure is confined when magma domes block volcanic vents following an eruption?
• Which outcome occurs when a fault's creep rate decreases?
• Which outcome commonly results where oceanic transform faults terminate near subduction zones?
