← GeographyWhich mechanism prevents earthquakes along a previously locked transform fault segment when slow creep occurs?
A)Reduced elastic strain accumulation✓
B)Increased rock fracture toughness
C)Elevated pore fluid pressure
D)Saturated surface sediment compaction
💡 Explanation
When slow creep occurs, aseismic slip reduces elastic strain accumulation because continuous movement mitigates the build-up of stress compared to the stick-slip behavior of locked faults. Therefore, reduced elastic strain accumulation, rather than increased fracture toughness, elevated pressure, or compaction, prevents subsequent earthquakes.
