← GeographyWhich risk increases when long-term creep along a transform fault locks energy without slippage?
A)Rapid increase in regional metamorphism
B)Episodic tremor and slip events
C)Increased probability of a megathrust earthquake✓
D)Widespread formation of kimberlite pipes
💡 Explanation
When creep along a transform fault is inhibited, elastic strain accumulates because frictional resistance exceeds stress, leading to a gradual increase in energy stored in the adjacent fault segments prone to rupture. Therefore increased probability of a megathrust earthquake results, rather than metamorphism, tremors, or kimberlite which depend on other geological processes.
