While rain is a common trigger, landslides can occur due to other factors as well. Statement 2 is correct as clay-rich soils become unstable when saturated, increasing the risk of landslides. Statement 3 is correct as earthquakes are well-known triggers for landslides due to ground shaking.<br \/>\n<\/section>\n<section id=\"pyq-key-points\">\nLandslides are mass movements occurring on slopes.
