Which outcome accelerated the collapse of some ancient hillside terracing under intense rainfall?

💡 Explanation

Increased pore water pressure reduces soil shear strength, causing landslides during rainfall because the increased water saturates the soil; therefore collapse accelerated, rather than remaining stable or slowly eroding if pore water pressure had been regulated.
