• Hurricanes, Typhoons & Cyclones- Hurricanes, typhoons, and cyclones refer to the same weather phenomenon, where a really large storm swirls in circles.

• Tsunamis- A tsunami consists of huge waves caused by either an underwater earthquake or volcanic eruption. In Japanese, the word means 'harbor wave.'

• Avalanches- An avalanche (also called a snowslide) is an event that occurs when a cohesive slab of snow lying upon a weaker layer of snow fractures and slides down a Man-made disasters can include hazardous material spills, fires, groundwater contamination, transportation accidents, structure failures, mining accidents, explosions and acts of terrorism. slope.
