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

Learning from the Past

Slide 17. 11, Learning from the Past (Source: NOAA)

The impact of natural disasters on human life in last century has changed due to increased knowledge, awareness, technology, and their applications; yet continuing dedication to mitigation and coastal management efforts are essential.

Preparing for the Future

Slide 17. 12, Preparing for the Future

Natural hazards cannot be managed, but human

development and growth in the coastal zone can through pro-active coastal management.
