Which risk increases when seismic waves weaken a large landslide-prone slope immediately after a major earthquake?

💡 Explanation

When seismic waves occur after an earthquake, the repeated stress weakens soil cohesion because shaking disrupts soil structure bonds potentially triggering slope failure. Therefore destabilization from reduced cohesion results, rather than vegetation growth, enhanced drainage, or groundwater recharge, as these need different triggering conditions.
