What Causes Rockfalls After Natural Disasters?
Rockfalls are sudden movements of loosened rock, often triggered by environmental events. Natural disasters increase the risk of slope failure by weakening rock formations and altering slope stability.
- Earthquakes – Seismic shaking can fracture rock masses, leading to immediate or delayed failure.
- Heavy Rainfall & Flooding – Water infiltration reduces slope strength, increasing the risk of rock detachment.
- Wildfires – Burned vegetation leaves slopes exposed, accelerating erosion and rockfall risk.
- Extreme Weather – Freeze-thaw cycles and wind events can degrade rock faces and dislodge unstable material.
