Which risk increases when bentonite clay along faults hydrates?

💡 Explanation

Increased landslide susceptibility results because fault hydration reduces soil cohesion via pore pressure increase, a process called effective stress reduction; therefore, slope destabilization increases rather than fault stress decreasing or seismic velocity increasing under such conditions.
