← GeographyWhich outcome results when sediment overburden exceeds pore pressure limits during subduction?
A)Episodic tremor and slip events ease
B)Megathrust earthquakes' frequency decreases
C)Seismic velocity within fault decreases
D)Increased risk of slow slip events✓
💡 Explanation
Pore pressure reduction due to overburden leads to increased effective stress, therefore promoting fault locking and stress accumulation which leads to slow slip events, rather than aseismic creep which relieves the stress continuously.
