How do earthquakes trigger landslides and rockfalls on mountainsides?
Shaking can weaken slopes by loosening rock, reducing friction, and shaking water-saturated soil. Steep or fractured slopes are most likely to collapse during strong ground motion.

why
Why do earthquakes sometimes cause landslides?
Shaking loosens slopes that are already steep, fractured, or waterlogged, reducing the force holding the material in place. Gravity then pulls the weakened slope downhill.
