← GeographyAlong a subduction zone, which outcome frequently results when the locked fault segment exceeds its rupture strength?
A)Episodic tremor and slip events✓
B)Increased mantle convection velocity
C)Enhanced plate buoyancy force
D)Accelerated seafloor spreading rates
💡 Explanation
Upon exceeding its rupture strength, elastic rebound causes episodic tremor and slip, because friction unlocks the fault, allowing slow slip and seismic tremors. Therefore, ETS events occur rather than a major earthquake, which happens when there is full rupture.
