How do earthquakes trigger landslides?
Quick Answer
Strong shaking can loosen rock and soil on steep slopes, causing them to fail suddenly. Wet ground, fractured rock, and steep terrain make landslides more likely.
The Full Story
Earthquakes can destabilize slopes by shaking loose blocks of rock and weakening soil layers. If a hillside is steep enough and already saturated or cracked, the ground may collapse into a landslide during or after the shaking. This is why mountainous regions often see secondary damage long after the main quake. Landslides can bury roads, dam rivers, and cut off communities. In some disasters, landslides are as dangerous as the earthquake itself.
