Understanding Natural Hazards

The video tutorial explains the difference between hazards and disasters, emphasizing that hazards become disasters when they cause harm. It highlights natural hazards like hurricanes and wildfires, and discusses how climate change exacerbates these events. The tutorial stresses the importance of mitigation strategies, such as building designs that withstand natural forces, to prevent hazards from becoming disasters.
