4. All regions have identical mitigation strategies with no variation based on specific hazards or local conditions

1. Oceanic crust is 5-10km thick, more dense, made of basalt, and subducts under continental crust, while continental crust is 30-70km thick, less dense, made of granite, and does not subduct, which explains why oceanic-continental convergence creates subduction zones ✓
