Natural Disasters

WithLouis Theodore, R. Ryan Dupont

This chapter contains five case studies that focus on the hazards/risks associated with the following natural disasters: Hurricanes, Floods, Earthquakes, Meteorites, Combined hurricanes and flooding. “Hurricane” is the name applied to a class of disasters that usually originates over oceans in certain regions near the equator, and particularly refers to those storms arising in the Caribbean Sea and Gulf of Mexico. A flood may be defined as an increase of flow of water that submerges land. Floods occur when soil becomes saturated from excessive rain and/or snow melt. An earthquake has also been referred to a quake, tremor, or as seismic actively. An earthquake produces vibrations at or near the Earth’s surface when rocks, in which elastic strain has increased, suddenly rupture and then rebound. A meteor is defined as a small solid body entering the Earth’s atmosphere from outer space. The chapter concludes with a relatively simple case study involving two natural disasters: a hurricane followed by flooding.
