Which outcome occurs when increased pore water pressure?

💡 Explanation

A reduction in effective normal stress on fault planes causes failure during earthquakes, linked to the principle of effective stress reduction. This occurs because the increased pore water pressure counteracts the clamping force; therefore, it lowers the frictional resistance, rather than increasing fault stability.
