Which outcome occurs when pressure exceeds competent rock strength along a transform fault?

A)Episodic tremor and slip (ETS)
B)Aseismic creep accelerates steadily
C)Stable sliding without fracturing
D)Elastic strain loading decreases linearly

💡 Explanation

Episodic tremor and slip occur when accumulated stress overcomes the shear strength, causing sudden slip; this is caused by stick-slip behavior. Therefore, ETS occurs rather than continuous creep, because the stress builds up until failure; stable sliding dissipates energy through other mechanisms.
