← GeographyWhich outcome results as increased pore water pressure impacts fault mechanics during subduction?
A)Episodic tremor and slow slip✓
B)Increased mantle plume upwelling
C)Enhanced metamorphic rock formation
D)Declining volcanic eruption frequency
💡 Explanation
Episodic tremor and slow slip occur due to elevated pore water pressure, weakening connections along the subduction fault via effective stress reduction, because friction becomes intermittent under fluid influence; therefore ETS is more likely rather than constant slip.
