Slide 17. 1, Lecture Outline
Introduction: Coastal Disaster Case Studies
Slide 17. 2, Introduction
Coastal Hazards can be defined as natural hazards that occur within the coastal zone. Hazards become disasters when they intersect the human coast. This session will look at several case study examples of coastal disasters.
The following disasters will be discussed in this session:
• Galveston Hurricane• Loma Prieta Earthquake• Hurricane Andrew• Hurricane Floyd
