- Example: Volcanoes are natural hazards, but if they erupt and cause harm to humans, it is a natural disaster.
Engineers and Natural Disasters
- Engineers must be familiar with natural hazards to understand their impact on design and community planning.
- They must know where natural hazards are likely to occur to help people survive and reduce the effect of natural disasters.
