Which outcome characterizes a deep-sea trench near a subduction zone undergoing sediment starvation?

💡 Explanation

Megathrust earthquakes increase on sediment-starved subduction zones because reduced sediment pore pressure decreases fault lubrication, facilitating stick-slip behavior, therefore promoting high-magnitude rupture events rather than steady creep behavior and smaller quakes.
