Which outcome occurs when sediment accumulation restricts fluid escape along a subduction zone?

💡 Explanation

Episodic, shallow, megathrust earthquakes occur because increased pore pressure reduces effective stress via Terzaghi's effective stress principle, leading to stick-slip behavior and sudden rupture. Therefore, unstable slip occurs rather than steady creep, because of increased stress from the excess sediment pore pressure.
